  • Counting values in data frame subject to conditions

    - by unixsnob
    I have been searching around and I cannot figure out how to sumarise the data I have in my data frame (subject to some ranges). I know that it can be done when applying some combination of daaply/taaply or table but I haven't been able to get the exact result I was expecting. Basically I want to turn this: part_no val1 val2 val3 2 1 2 3 45.3 2 1 3 4 -12.3 3 1 3 4 99.3 3 1 5 2 -3.2 3 1 4 3 -55.3 Into this: part_no val3_between0_50 val3_bw50_100 val3_bw-50_0 val3_bw-100_-50 2 1 0 0 1 0 3 0 1 0 1 1 This is dummy data, I got a lot more rows, but the idea is the same. I just want to count the number of values for a participant that meet certain condition. If anyone could explain it sort of step by step, I would really appreciate it. I saw lots of different little posts around, but none do exactly this and my attempts only got me half way there. Like using table, etc. Thanks!

  • g++ library search failure

    - by Frederick
    I have a directory structure as below: / | +--- /lib | libsomething.a | libsomething.so | +----/obj anObjFile.o When I run the following command from within the obj directory: g++ -L../lib -lsomething anObjFile.o I get undefined reference errors. Apparently gcc is failing to locate libsomething.a. But now if I delete libsomething.so and then rerun the command, linking succeeds. As per gcc documentation -lsomething should expand to libsomething.a. Then why is presence of libsomething.so causing the library search to fail? Also, how can I resolve this problem? I'm on Linux Mint 12 with gcc version 4.6.1.

  • As a Web Developer, how complicated is your average job compared to this?

    - by Daniel S
    I'm 16 years old, and I've recently started to do freelance jobs. I've been playing with PHP since I was 12 and think that I can code reasonably well. So far, I've created a library for fetching info from LinkedIn profiles and some WordPress plugins. However, right now this client wants me to convert an HTML template into a WordPress theme for use as a website. I feel this is a tad easy. As professional web programmers, are most assignments harder than this?

  • Minimizing distance to a weighted grid

    - by Andrew Tomazos - Fathomling
    Lets suppose you have a 1000x1000 grid of positive integer weights W. We want to find the cell that minimizes the average weighted distance.to each cell. The brute force way to do this would be to loop over each candidate cell and calculate the distance: int best_x, best_y, best_dist; for x0 = 1:1000, for y0 = 1:1000, int total_dist = 0; for x1 = 1:1000, for y1 = 1:1000, total_dist += W[x1,y1] * sqrt((x0-x1)^2 + (y0-y1)^2); if (total_dist < best_dist) best_x = x0; best_y = y0; best_dist = total_dist; This takes ~10^12 operations, which is too long. Is there a way to do this in or near ~10^8 or so operations?

  • I'm a PHP programmer. Should I learn Java to improve my skills?

    - by user326068
    I think the title says everything. I'm a PHP programmer. Maybe it's interesting that I do php programming at work, but that's not full time. I'm still a student until '12 and I'll go to university after this before I'll start with my real life as programmer. Now I'm asking myself whether it would be a good way to do some java to improve my skills in OOP and other things that are better in Java then in PHP and I can learn their to port them to PHP.

If row and columns increases how to handle it? This is not homework. I was learning solving complex structure so I need to understand it by some guidance.

  • In a shared .iml file, what should the jdkName be for an IntelliJ IDEA Plugin SDK?

    - by bolinfest
    I work on a team where we commit our .iml files in version control so that everyone can use them. We have an .iml file for a plugin module, which includes the following: <orderEntry type="jdk" jdkName="IDEA IC-117.798" jdkType="IDEA JDK" /> however, that only works for people who are using that version (IC-117.798) of IntelliJ (some are on 12, some are using the ultimate edition, etc.) Is there any sort of variable like $INTELLIJ_SDK that could be used for the value of jdkName so that the .iml file is valid regardless of which version of IntelliJ you are using?

    - by rajeeesh
    I had a commenting application in my web site. The comments will store in a MySQL table . table structure as follows id | Comment | user | created_date ------------------------------------------------------ 12 | comment he | 1245 | 2012-03-30 12:15:00 ------------------------------------------------------ I need to run a query for listing all the comments after a specific time. ie .. a query like this SELECT * FROM comments WHERE created_date > "2012-03-29 12:15:00" ORDER BY created_date DESC Its working fine.. My question is if I got a 1-2 lakh entry in this table is this query is sufficient for the purpose ? or this query will take time to execute ? In most cases I have to show last 2 days data + periodically ( interval of 10 mins ) checking for updates with ajax from this table ... Please help Thanks

  • Using a string as an object reference

    - by user317362
    I currently have a Javascript function that uses a string to reference an object name and acces its properties. I'm currently using eval() to get the the desired effect which I know is very, very wrong. Here is an example of how I'm currently achieving what I want: var stringToObjectRef = function() { var myTestVar = "myTestObject"; var myTestObject = { 'item1' : 100, 'item2' : 12, 'item4' : 18 }; var myValue = eval(myTestVar + '.item1'); alert(myValue); }(); I've tried using something like [myTestVar].item1, but this returns undefined. What is the correct syntax to achieve this? Thanks in advance.

  • eliminating noise/spikes

    - by tgv
    I have a measurement data with similar positive and negative values which should be like: ReqData=[0 0 -2 -2 -2 -2 -2 -2 0 0 0 -2 -2 -2 -2 0 0 2 2 2 2 2 2 0 0 2 2 2 2 2 0 0 2 2 2 2 2 0 0 2 2 2 0 0]' However, there are some measurement noises in the data - so the real data is like this: RealData=[0 0 -2 -2 -2 -2 -2 -2 0 0 0 -2 -2 -2 -2 0 0 2 2 2 2 -4 -1 0 0 2 2 2 2 -7 0 0 2 2 2 2 -1 0 0 2 2 2 0 0]' How do I remove the end noise from the RealData and convert it into ReqData using Matlab? How do I find the start and stop indexes of each set of positive or negative data and split them using Matlab? For instance, ansPositive = [3,8, 12, 15]' and ansNegative = [18, 23, 26, 30, 33, 37, 40, 42]'.

  • Easiest way to keep SSRS child elements in the same relative position when the parent is re-positioned?

    - by Mac
    I am trying to revise the layout of an SSRS report where I have several textboxes that are child elements of a rectangle. When I reposition the parent rectangle down by x, all of the child textboxes maintain the same absolute position. Their "Location" (defined relative to the parent) decreases by x. I then need to reposition the child textboxes. Additionally, if any of these ever has a negative "Location" then the parent rectangle is then repositioned back up by x. What is the easiest way to move everything in unison? I can Control-click everything and then drag them or use the arrow keys, but I want to position everything with precision and the "Location" field in the Properties window disappears when selecting more than one item. Is there a way I can avoid individually computing and typing in every "Location" value every time I have a small layout change? I am using SSRS (11.0.3360.12) within the Visual Studio 2012 Shell. Thanks!
