  • Writing a script for reading many .csv files with similar filenames

    - by wahalulu
    I have several .csv files with similar filenames except a numeric month (i.e. 03_data.csv, 04_data.csv, 05_data.csv, etc.) that I'd like to read into R. I have two questions: Is there a function in R similar to MATLAB's varname and assignin that will let me create/declare a variable name within a function or loop that will allow me to read the respective .csv file - i.e. 03_data.csv into 03_data data.frame, etc.? I want to write a quick loop to do this because the filenames are similar. As an alternative, is it better to create one dataframe with the first file and then append the rest using a for loop? How would I do that?

  • How to correctly migrate urls from custom asp.net solution to Wordpress?

    - by Marek
    I have a web site built using asp.net with ugly URLs like /DisplayContent.aspx?id=789564. I know how to migrate the database, but the Wordpress urls will be (naturally) different. Can I simply write some mapping or do I have to include a rewrite rule for each subpage (300 pages) in .htaccess? Should I provide a rewrite rule for each existing page that would transform a full old url to the known new url, like for example: /DisplayContent.aspx?id=789798 -> /2010-5-10/Title-Of-The-Post Even if I manage to migrate the URLs, the structure of the HTML for the new content will naturally be different. How does this affect SEO? Should I run asp.net and wordpress side by side and issue the redirects from the asp.net application? What is the most efficient solution to this kind of migration of URLs without doing PHP programming?

  • In PHP can I check a boolean on a function call?

    - by Chris
    I have a function which checks the passed value and returns false or true, if false I want it to add something to an array. The code I've written is below. if(!check_input($_POST['username'])){ $errors[] = "Username"; } Right now it adds to my array anyway, regardless of what is entered in the form. Is the way I've written that the correct way to check if the return from check_input() is false? I've checked the function's logic by altering the returns to echoes and it's returning the correct value, I'm just not sure if I'm checking it wrong. I'd previously attempted to write it as $X=check_input etc, and then if(check_value == false) but that doesn't seem to give me the desired result either. Hmmm a quick pointer please!

  • C++ IDE for OSX

    - by gprime
    When i was at university i wrote a lot of C++. I primarily used either Visual Studio (at the time it was version 6) or VIM (if i was on linux) as an editor to write my code. Since i have graduate and have been working primarily in web programming i have stopped writing C++. Since i graduated i have also bought myself and started using my Mac exclusively. I am now starting to get back to my C++ coding (just for fun) and would like an opinion on good IDE's for Mac. I am currently using xCode which seems kinda cool because it has everything built into it. Do any of you have any other IDE's that you would suggest that i give a shot or should i just stick to xCode?

  • does anyone see any issues with this thread pattern?

    - by prmatta
    Here is a simple thread pattern that I use when writing a class that needs just one thread, and needs to a specific task. The usual requirements for such a class are that it should be startable, stopable and restartable. Does anyone see any issues with this pattern that I use? public class MyThread implements Runnable { private boolean _exit = false; private Thread _thread = null; public void start () { if (_thread == null) { _thread = new Thread(this, "MyThread"); _thread.start(); } } public void run () { while (_exit) { //do something } } public void stop () { _exit = true; if (_thread != null) { _thread.interrupt(); _thread = null; } } } I am looking for comments around if I am missing something, or if there is a better way to write this.

  • Troubles with NSString writeToFile

    - by Jesse
    Hi everyone, I have been working on a simple text editor in Cocoa/Objective-C for a practice project and I have come across an error that I would never have expected. I have an NSString for my file's contents as well as an NSString for it's path. When I attempt to write the contents to a file, I use the following method: [FileContents writeToFile: CurrentFileName atomically: NO encoding: NSStringEncoding error: nil]; I've used this method many times without error yet today, I am getting an error: "Expected expression before 'NSStringEncoding'" If anyone can help me out with this it would be greatly appreciated. I can't figure out what could be causing the error. Thanks a lot!

  • Manually manipulating ArrayList

    - by jsan
    I have an assignment where I have to create a deque, however I am not allowed to use any built-in classes or interfaces. I am implementing my deque using an array list. My problem is that when I have to, for instance, add to the beginning of the array list (beginning of the queue), i am not allowed to do this: public void addFirst(ArrayList<Integer> array) { array.add(0, int); } Is there a way to do this without using the add() function? Such as manually adding to the front and shifting the rest of the array to the right? Or maybe creating a new array list and copying...I'm not sure. Any help would be great; I have a bunch of functions to write, and getting the first one done will definitely put me in the right direction. Thanks

  • How to group rows into two groups in sql?

    - by user1055638
    Lets say I have such a table: id|time|operation 1 2 read 2 5 write 3 3 read 4 7 read 5 2 save 6 1 open and now I would like to do two things: Divide all these records into two groups: 1) all rows where operation equals to "read" 2) all other rows. Sum the time in each group. So that my query would result only into two rows. What I got so far is: select sum(time) as total_time, operation group by operation ; Although that gives me many groups, depending on the number of distinct operations. How I could group them only into two categories? Cheers!

  • Iterating through facebook comments JSON object failing

    - by user1594304
    I tried the option of students.item["http://www.myurl.com"].comments.data.length. However, the item["http://www.myurl.com"] call is not working. If I take out the URL from JSON object and write the iterator with students.comments.data, it works. Here is my code, any help highly appreciated. var students = { "http://www.myurl.com":{ "comments":{ "data" : [ { "id": "123456778", "from": { "name": "XYZ", "id": "1000005" }, "message": "Hey", "can_remove": false, "created_time": "2012-09-03T03:16:01+0000", "like_count": 0, "user_likes": false } ] } } } var i=0 var arrayObject = new Array(); alert("Parsing 2: "+students.item["http://www.myurl.com"].comments.data.length); for(i=0;i<students.item["http://www.myurl.com"].comments.data.length;i++) { alert("Parsing 1: "+i); arrayObject.push(students.item["http://www.myurl.com"].comments.data[i].id); arrayObject.push(students.item["http://www.myurl.com"].comments.data[i].message); arrayObject.push(students.item["http://www.myurl.com"].comments.data[i].created_time); }

  • need a virtual template member workaround

    - by yurib
    Hello, I need to write a program implementing the visitor design pattern. The problem is that the base visitor class is a template class. This means that BaseVisited::accept() takes a template class as a parameter and since it uses 'this' and i need 'this' to point to the correct runtime instance of the object, it also needs to be virtual. I'd like to know if there's any way around this problem. template <typename T> class BaseVisitor { public: BaseVisitor(); T visit(BaseVisited *visited); virtual ~BaseVisitor(); } class BaseVisited { BaseVisited(); template <typename T> virtual void accept(BaseVisitor<T> *visitor) { visitor->visit(this); }; // problem virtual ~BaseVisited(); }

  • public (static) swap() method vs. redundant (non-static) private ones...

    - by Helper Method
    I'm revisiting data structures and algorithms to refresh my knowledge and from time to time I stumble across this problem: Often, several data structures do need to swap some elements on the underlying array. So I implement the swap() method in ADT1, ADT2 as a private non-static method. The good thing is, being a private method I don't need to check on the parameters, the bad thing is redundancy. But if I put the swap() method in a helper class as a public static method, I need to check the indices every time for validity, making the swap call very unefficient when many swaps are done. So what should I do? Neglect the performance degragation, or write small but redundant code?

  • Create a picture with GD containing other images

    - by Jensen
    Hi, I would like to create a picture in PHP with GD composed by different other pictures. For example I have 6 pictures (or more) and I would like to create ONE picture who contain these different pictures. The Difficulty is that my final picture must have a fixed width and height (304x179), so if the different pictures are too big they must be cut. This is an example from IconFinder : This picture is composed by 6 images, but the 3rd bird (green) is cutted, and the 4, 5 and 6 are cutted in the bottom. This is what I want, can you give me some help to write this code in PHP ? Thanks

Note: I know there are a host such effects out there, i just want to know how do i create a simple centered div with transparent background behind. So please don't suggest any pre-made solution, would be great if you could write sample code for that. Thanks

  • How do you get 100% code coverage with guards in Haskell?

    - by dan_waterworth
    I'm trying to get (and prove) 100% test coverage for some code I'm writing in Haskell using HPC. However if I write something like this: fac n | n > 0 = n * (fac (n - 1)) | otherwise = 1 Then the second expression of the guard statement has always True tagged to it. What is the easiest way to overcome this in the general case? edit: Just to clarify. This code: fac n = if n > 0 then n * (fac (n - 1)) else 1 Works fine with HPC, (running it gives 100% code coverage). I'm basically suffering from this problem: http://hackage.haskell.org/trac/ghc/ticket/3175

  • c++ classes & lua

    - by anon
    I want to have C++ objects that I can read/write in both C++ & Lua. I have looked at: http://www.lua.org/pil/28.html However, I do not like that solution, since my objects have constructors & destructors (and they are important as I use RAII and these take care of reference counts). What I don't like in the PIL solution is that the object is allocated in Lua's heap. What i want instead, is to create hte C++ object on my own, and just have lua have a way to do get/set on them. Does anyone have a good tutorial/link on this? Tanks!

  • Android: how to have app talk to a web page, ie send gps location

    - by Ted pottel
    I'm trying to write a app, where a webpage will have a button that when press will give the GPS location of the phone. I was going to have the android app create a thread that waits on a scket connection. The issue is that 1. Getting the ip addrs of the phone 2. I was told this would really drain the battery I was also thinking about having the phone send the gps location to a webserver like evrry 10 seconds. This sort of seams like a waste of bandwidth. Is there a good way to do this?

  • Syntax error in INSERT INTO statement in c# oledb?

    - by sameer
    I am having a table called SubMaster_Accounts, which contains 9 fields. In which I want to insert data to some fields and i want to store some other fields as NULL. I tried to write the query using query string, The sql query works perfectly when i insert the data for all the fields, but when i insert data as NULL to some of the fields it shows syntax error in Insert command. The fields which i want to insert as NULL are not constraints. How can i do it? This is my query string. insert into SubMaster_Account ([SMcode], [MSname], [Sname], [Openbalrs], [Openbalrs1], [Openbalmet], [Openbalmet1], [Creditdays], [Sdesc]) values ('" + SMcode + "','" + MSname + "','" + Sname + "'," + Openbalrs + ",'" + Openbalrs1 + "'," + Openbalmet + ",'" + Openbalmet1 + "'," + Creditdays + ",'" + Sdesc + "')

  • Multiple column Union Query without duplicates

    - by Adam Halegua
    I'm trying to write a Union Query with multiple columns from two different talbes (duh), but for some reason the second column of the second Select statement isn't showing up in the output. I don't know if that painted the picture properly but here is my code: Select empno, job From EMP Where job = 'MANAGER' Union Select empno, empstate From EMPADDRESS Where empstate = 'NY' Order By empno The output looks like: EMPNO JOB 4600 NY 5300 MANAGER 5300 NY 7566 MANAGER 7698 MANAGER 7782 MANAGER 7782 NY 7934 NY 9873 NY Instead of 5300 and 7782 appearing twice, I thought empstate would appear next to job in the output. For all other empno's I thought the values in the fields would be (null). Am I not understanding Unions correctly, or is this how they are supposed to work? Thanks for any help in advance.

  • Finding data file location while using Microsoft Test Framework

    - by Nair
    I have been using NUnit and now I am switching to the Microsoft Unit Test frame work. In my test project I have a folder called TestData and I kept all my test input data files there. I want to use that files for my unit testing. In my test code, I am using Application name space and assembly name space but I can not get to the data folder directly until unless I write a code to find and replace some string to point to the data folder. I am sure someone might have run into the same problem, is the solution to change the path through program or is there a API call which will let us get to executing assembly folders? Thanks,

  • Send data over telnet without pressing enter

    - by Matt
    I've recently started messing around with Java sockets and telnet... I want the user to be able to connect to the server, just type a letter and have it sent to the server, without pressing enter to send it. I'm sure there's no way for the server to set this up, but maybe telnet has a parameter or something which could allow this? Maybe if I got the user to type stty cbreak or stty raw before running telnet, this would work? (UNIX only, I know!) If I can get telnet to do this then it saves me having to write a special client just for this feature...
