  • Extract information from conditional formula

    - by Ken Williams
    I'd like to write an R function that accepts a formula as its first argument, similar to lm() or glm() and friends. In this case, it's a function that takes a data frame and writes out a file in SVMLight format, which has this general form: <line> .=. <target> <feature>:<value> <feature>:<value> ... <feature>:<value> # <info> <target> .=. +1 | -1 | 0 | <float> <feature> .=. <integer> | "qid" <value> .=. <float> <info> .=. <string> for example, the following data frame: result qid f1 f2 f3 f4 f5 f6 f7 f8 1 -1 1 0.0000 0.1253 0.0000 0.1017 0.00 0.0000 0.0000 0.9999 2 -1 1 0.0098 0.0000 0.0000 0.0000 0.00 0.0316 0.0000 0.3661 3 1 1 0.0000 0.0000 0.1941 0.0000 0.00 0.0000 0.0509 0.0000 4 -1 2 0.0000 0.2863 0.0948 0.0000 0.34 0.0000 0.7428 0.0608 5 1 2 0.0000 0.0000 0.0000 0.4347 0.00 0.0000 0.9539 0.0000 6 1 2 0.0000 0.7282 0.9087 0.0000 0.00 0.0000 0.0000 0.0355 would be represented as follows: -1 qid:1 2:0.1253 4:0.1017 8:0.9999 -1 qid:1 1:0.0098 6:0.0316 8:0.3661 1 qid:1 3:0.1941 7:0.0509 -1 qid:2 2:0.2863 3:0.0948 5:0.3400 7:0.7428 8:0.0608 1 qid:2 4:0.4347 7:0.9539 1 qid:2 2:0.7282 3:0.9087 8:0.0355 The function I'd like to write would be called something like this: write.svmlight(result ~ f1+f2+f3+f4+f5+f6+f7+f8 | qid, data=mydata, file="out.txt") Or even write.svmlight(result ~ . | qid, data=mydata, file="out.txt") But I can't figure out how to use model.matrix() and/or model.frame() to know what columns it's supposed to write. Are these the right things to be looking at? Any help much appreciated!

  • Why is UIApplicationWillChangeStatusBarFrameNotification not sent when the in-call status bar is sho

    - by Sbrocket
    I've been trying to listen for changes in the status bar height – such as when the in-call status bar is shown or hidden – by listening for the UIApplicationWillChangeStatusBarFrameNotification notification to be sent. Fairly straightforward code here... [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(statusBarWillChangeFrame:) name:UIApplicationWillChangeStatusBarFrameNotification object:nil]; But the notification never seems to be sent in that case, either on the Simulator by using the "Toggle In-Call Status Bar" option or on the device when a call ends with the application open. In addition, the similar UIApplicationDelegate method is not called. According to the documentation, UIApplicationWillChangeStatusBarFrameNotification Posted when the application is about to change the frame of the status bar. The userInfo dictionary contains an NSValue object that encapsulates a CGRect structure expressing the location and size of the new status bar frame. Use UIApplicationStatusBarFrameUserInfoKey to access this value. Can anyone explain why this notification is not being sent in response to the in-call status bar being shown or hidden? According to the documentation, it should be.

  • Resizing screenshots/screen captures for inclusion in Beamer

    - by Stephen
    Sorry, this may or may not be a programming question directly, but I am trying to resize screenshots with Imagemagick and Gimp to include in a Beamer presentation, but it comes out even blurrier than the resizing done by LaTeX. For instance, in Beamer I might have a command to rescale the image \includegraphics[width=.5\textwidth]{fig.png}. Using something like \begin{frame} \message{width = \the\textwidth} \message{height = \the\textheight} \end{frame} I have gotten the \textwidth and \textheight parameters in points (345.69548, 261.92444). So I have a script (in Python) that sends a system call to Imagemagick: 'convert %s -resize %.6f@ resized_%s' % (f,a,f) where a is calculated as \textwidth*\textheight*0.5**2. When I then go back into my Beamer presentation and include the resized figure, \includegraphics{resized_fig.png}, the size looks approximately correct but it's super-blurry. I also tried resizing in Gimp (using the GUI) but no luck either... help? Thanks...

  • OpenGL es 2.0 Read depth buffer

    - by Brian
    Hi! As far as i know, we can't read the Z(depth) value in OpenGL ES 2.0. So I am wondering how we can get the 3D world coordinates from a point on the 2D screen? Actually I have some random thoughts might work. Since we can read the RGBA value by using glReadPixels, how about we duplicate the depth buffer and store it in a color buffer(say ColorforDepth). Of course there need to be some nice convention so that we don't lose any information of the depth buffer. And then when we need a point's world coordinates , we attach this ColorforDepth color buffer to the framebuffer and then render it. So when we use glReadPixels to read the depth information at this frame. However, this will lead to 1 frame flash since the colorbuffer is a weird buffer translated from the depth buffer. I am still wondering if there is some standard way to get the depth in OpenGL es 2.0? Thx in advance!:)

  • Why is my toolbar not visible when in landscape mode?

    - by mr-sk
    My aim was to get the application functioning in both landscape and portrait mode, and all I could figure out to do it was this code below. The app was working fine in portrait, but when switched to landscape, the text wouldn't expand (to the right) to fill up the additional space. I made sure my springs/struts where set, and that the parents had "allowResizing" selected in IB. Here's what I've done instead: - (void) willAnimateSecondHalfOfRotationFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation duration: (NSTimeInterval)duration { UIInterfaceOrientation toInterfaceOrientation = self.interfaceOrientation; if (toInterfaceOrientation == UIInterfaceOrientationPortrait) { self.myView.frame = CGRectMake(0.0, 0.0, 320.0, 480.0); } else { self.myView.frame = CGRectMake(0.0, 0.0, 480.0, 256.0); } } Note that it looks just fine in portrait mode (toolbar appears): But the toolbar is gone in landscape mode: Any ideas?

  • Why Does the iPad Toolbar Refuse to Reappear When Orientation Changes?

    - by dugla
    I have a fullscreen OpenGL iPad app that behaves correctly for all orientation changes. I now want to add a UIToolbar programmatically and while it appears correctly in launch orientation - portrait in the Xcode simulator - it dissapears when the orientation changes to landscape. Change the orientation back to portrait and the Toolbar reapppears. Huh? - (void)loadView { NSLog(@"EAGL ViewController - load View"); CGRect frame = [[UIScreen mainScreen] applicationFrame]; EAGLView *eaglView = [[[EAGLView alloc] initWithFrame:frame] autorelease]; self.view = eaglView; [[NSBundle mainBundle] loadNibNamed:@"Toolbar" owner:self options:nil]; NSLog(@"%@", [[self.toolbar class] description]); [self.view addSubview:self.toolbar]; [self.view bringSubviewToFront:self.toolbar]; } What have I failed to do here? Thanks, Doug

  • iPad leak - NSPushAutoreleasePool

    - by Tim Bowen
    We are getting a sizable leak (16kb) that is proving very difficult to eliminate. The responsible library is Foundation and the Responsible frame is NSPushAutoreleasePool. This leak does not appear on the iPhone, only the iPad. We get the following stack trace: 9 libSystem.B.dylib thread_assign_default 8 libSystem.B.dylib _pthread_start 7 WebCore RunWebThread(void*) 6 CoreFoundation CFRunLoopRunInMode 5 CoreFoundation CFRunLoopRunSpecific 4 CoreFoundation __CFRunLoopDoObservers 3 WebCore WebRunLoopLock(__CFRunLoopObserver*, unsigned long, void*) 2 Foundation NSPushAutoreleasePool 1 Foundation _NSAPAddPage 0 libSystem.B.dylib malloc We're getting a similar one in the frame NSAutoReleasePool. We've checked everywhere in the code we create an autoreleasepool to make sure we're releasing it. Since none of this is our code I'm not sure how to proceed. Thanks in advance.

  • Adding UIViews with dynamic heights iphone

    - by Andy Jacobs
    in my viewcontroller's view i need to add a couple of custom UIView's, i do that in the loadView method so in my custom uiview's drawRect method i add a couple of UILabel's. in my viewcontroller's view i need to add all those custom UIView's underneath each other but i don't know what their height is sometimes 20px, 40px, 60px, depending on the outcome of the drawRect so when i init my custom UIView i give it a frame height of lets say 50.. but when the drawRect is done and it's only 20, 50 is too much so i need to adjust the frame height but how can i determine what's the visible height of the custom UIView and where can i catch it in my viewcontroller when the custom uiview has finished his drawRect method is there some kind of autoresize and where do i catch it in my viewcontroller, so i can position the custom uiview right under neath each other.

  • Smooth Error in qplot from ggplot2

    - by Jared
    I have some data that I am trying to plot faceted by its Type with a smooth (Loess, LM, whatever) superimposed. Generation code is below: testFrame <- data.frame(Time=sample(20:60,50,replace=T),Dollars=round(runif(50,0,6)),Type=sample(c("First","Second","Third","Fourth"),50,replace=T,prob=c(.33,.01,.33,.33))) I have no problem either making a faceted plot, or plotting the smooth, but I cannnot do both. The first three lines of code below work fine. The fourth line is where I have trouble: qplot(Time,Dollars,data=testFrame,colour=Type) qplot(Time,Dollars,data=testFrame,colour=Type) + geom_smooth() qplot(Time,Dollars,data=testFrame) + facet_wrap(~Type) qplot(Time,Dollars,data=testFrame) + facet_wrap(~Type) + geom_smooth() It gives the following error: Error in [<-.data.frame(*tmp*, var, value = list(NA = NULL)) : missing values are not allowed in subscripted assignments of data frames What am I missing to overlay a smooth in a faceted plot? I could have sworn I had done this before, possibly even with the same data.

  • How to flip the origin.y of an CGRect?

    - by mystify
    I'm trying to draw an UIImageView, but the frame's origin is wrong when I flip the coordinate system for drawing not upside-down. CGRect imgRect = imgView.frame; imgRect.origin.y += 10.0f; CGContextTranslateCTM(context, 0.0f, imgRect.size.height); CGContextScaleCTM(context, 1.0f, -1.0f); CGContextDrawImage(context, imgRect, imgView.image.CGImage); like you can see I move the image down by 10, but instead of going down by 10, it goes UP by 10. That's completely unlogical since I had actually inverted the wrong coordinate system to look exactly like the one in UIView, right? What to do about it?

  • playing only part of a sound using FMOD

    - by carneades
    I'm trying to play only part of a sound using FMOD, say frames 50000-100000 of a 200000 frame file. I have found a couple of ways to seek forward (i.e. to start playback at frame 50000) but I have not found a way to make sure the sound stops playing at 100000. Is there any way FMOD can natively do this without having to add lbsndfile or the like into the picture? I should also mention that I am using the streaming option. I have to assume that these sounds are arbitrarily large and cannot be comfortably/quickly loaded into memory.

  • Subview position issue after UIOrientation (rotation) change

    - by asadqamber
    I have a viewController and have added a subview in it programatically. secondView.autoresizingMask = UIViewAutoresizingFlexibleWidth; [self.view addSubview:secondView]; I guess when the device rotates, my mainViewController knows that orientation changed, but the subview (secondView) inside the mainViewController does not know this, so I change its frame to landscape size in willRotateToInterfaceOrientation. secondView.frame = CGRectMake(0, 0, 480 , 260); This does not set in the correct position, it's 11 px below the NavigationBar. Why does it start from 11 px below the navigation bar? The navigation bar shrinks when we move from portrait to landscape mode and its because of this that my subview is 11px below.

  • Hiding iPhone Status Bar pulls my tableViews up by 20px

    - by JustinXXVII
    When doing an asynchronous HTTP request, I hide the iPhone status bar and animate in my own custom UIViewController to show upload status. So instead of seeing signal strength, carrier, time and battery life, the user gets messages based on the progress of the HTTP request. My status bar is exactly 20px high, and fits nicely where the status bar used to be. When the HTTP activity is done, the custom view animates out and the iPhone status bar animates back in. I would like to just avoid hiding the iPhone status bar completely, and instead bring my custom view ON TOP of the status bar. Currently, if I invoke my custom view animation and keep the iPhone status bar set to visible, my custom view is behind it. This is the code I have: -(void) animateStatusBarIn { CGRect statusFrame = CGRectMake(0.0f, -20.0f, 320.0f, 20.0f); UploadStatusBar *statusView = [[UploadStatusBar alloc] initWithNibName:@"UploadStatusBar" bundle:nil]; self.status = statusView; [statusView release]; status.view.frame = statusFrame; [[UIApplication sharedApplication] setStatusBarHidden:YES animated:YES]; [window addSubview:status.view]; [UIView beginAnimations:@"slideDown" context:nil]; [UIView setAnimationDuration:0.3]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(animationFinished:)]; status.view.frame = CGRectMake(0.0f, 0.0f, 320.0f, 20.0f); [UIView commitAnimations]; } -(void) animateStatusBarOut { [UIView beginAnimations:@"slideUp" context:nil]; [UIView setAnimationDuration:0.3]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(animationFinished:)]; status.view.frame = CGRectMake(0.0f, -20.0f, 320.0f, 20.0f); [UIView commitAnimations]; } -(void)animationFinished:(NSString *)name { if ([name isEqualToString:@"slideDown"]) { } if ([name isEqualToString:@"slideUp"]) { [[UIApplication sharedApplication]setStatusBarHidden:NO animated:YES]; [status.view removeFromSuperview]; } } Without the [[UIApplication sharedApplication]setStatusBarHidden:YES animated:YES] you can't see my custom view. How can I get my custom view to just appear on top of the status bar so I don't have to hide it? Thank you!

  • A function's static and dynamic parent

    - by legends2k
    I'm reading Thinking in C++ (vol. 2): Whenever a function is called, information about that function is pushed onto the runtime stack in an activation record instance (ARI), also called a stack frame. A typical stack frame contains (1) the address of the calling function (so execution can return to it), (2) a pointer to the ARI of the function’s static parent (the scope that lexically contains the called function, so variables global to the function can be accessed), and (3) a pointer to the function that called it (its dynamic parent). The path that logically results from repetitively following the dynamic parent links is the dynamic chain, or call chain I'm unable to comprehend what the author means as function's static and dynamic parent. Also am not able to differentiate between item 1, 2 or 3. They all seem to be the same. Can someone please explain this passage to me?

  • iPhone: [subview release] removes my subview from the display

    - by Stefan Klumpp
    I have these two pieces of code. The first one works perfectly: UIView *tmp = [[UIView alloc] initWithFrame:CGRectMake(0.0f, 60.0f, 296.0f, 44.0f)]; [self.dynamicView addSubview:tmp]; [tmp release]; The second one is pretty much the same, but the view doesn't show up. CommentBox *commentBox = [[CommentBox alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 296.0f, 44.0f)]; [self.dynamicView addSubview:commentBox]; [commentBox release]; // Why does this remove the view? If I remove the [commentBox release] the view surprisingly appears. But I don't see a different between these two code snippets. The init for the CommentBox looks like this: - (id)initWithFrame:(CGRect)frame { if ((self = [super initWithFrame:frame])) { // Load the nib: NSArray *nibObjects = [[NSBundle mainBundle] loadNibNamed:@"CommentBox" owner:self options:nil]; self = [nibObjects objectAtIndex:0]; } return self; }

  • Odd values/movement with UITouch and CGPoint.

  • Displaying webcam feed using opencv and python

    - by Mitch
    Hi ive been trying to create a simple program with python which utilises opencv to get a video feed from my webcam and display it on the screen. I know im partly there because the window is created and the light on my webcam flicks on, but it just doesnt seem to show anything in the window. hopefully someone can explain what im doing wrong. import cv cv.NamedWindow("w1", cv.CV_WINDOW_AUTOSIZE) capture = cv.CaptureFromCAM(0) def repeat(): frame = cv.QueryFrame(capture) cv.ShowImage("w1", frame) while True: repeat() on an unrelated note, i have noticed that my webcam sometimes changes its index number in cv.CaptureFromCAM and sometimes i need to put in 0, 1 or 2 even though i only have one camera connected and i havnt unplugged it (i know because the light doesnt come on unless i change the index). is there a way to get python to determine the correct index? thanks Mitch

  • Cannot format first column in WxPython's ListCtrl

    If I set the format of the first column in a ListCtrl to align centre (or align right) nothing happens. It works for the other columns.

  • CLR debugger and 'var'

    - by Ken
    I'm using the CLR debugger (version 8, from "Visual Studio 2005") to debug some C# code. I can step through my code, but for many variables, the debugger won't show me its value. That is, if I type it in the "Immediate" frame or add it to the "Watch" frame, it says "Unable to evaluate the expression.". It seems to do this a lot for var variables, but I'm also seeing it for parameters and properties, too. I have not been able to figure out what the pattern is. Is there a rule for when it can display the value of a variable? Is there something I need to do to my code, or in my build script, to make the debugger able to view variables? Or is there a hidden debugger setting?
