Dear R helpers, I wish to use the "sum" operator for each row of a data frame. However, it appears that the operator acts on the entire data frame, over all columns. What is the best way to obtain row- wise operation? The following code shows my attempts so far, and their problems:- test1=array(rbinom(120,1,0.5),c(20,3)) test1[,3]=NA sum(test1[,1:2]) test1[,3][sum(test1[,1:2])>=2]=1

Hi folks, I have imported data from an Excel spreadsheet. Columns in that spreadsheet are named "name", "x", and "y", and several sets of those columns appear in the worksheet. For example: name x y name x y test1 1 3 test2 4 4 test1 2 2 test2 5 5 test1 3 1 test2 6 6 When I import these data into R, into a dataframe, I end up with something like this:

Hi I have this vector of strings. MyData <- c("Test1","Test2","I(Test1^2)","I(Test2^3)","I(Test1.Test2^2)") where I want to extract only the text after "I(" and before "^" so that the string returned only contain c("Test1","Test2","Test1.Test2") I am not very skilled in the use of matching

Dear R Group I was trying to use the triangle.test function in SensoMineR and strangely i encounter a error in the output of preference matrix from the analysis. To illustrate, pl see the following dataframe of a design with the response and preference collected as shown below: design<-structure(list(`Product X` = c(3, 1, 4, 2, 4, 2, 1, 3, 4, 2, 4, 2, 1, 3, 4, 2, 4, 2, 3, 1), `Product Y` =

Hi all, I decided to check the responsiveness of the pure Ruby vs C extension versions of win32-changenotify. I setup this little file generator program: a = [] 10.times{ |n| a << Thread.new{ File.open("File_#{n}", ''w''){ |fh| fh.puts "test #{n}" } } } a.each{ |t| t.join } The pure Ruby version did not do so well. In some cases it

Hi All, I installed OpenSUSE 11.0, updated samba server to 3.2.4 version. Added two users in linux and samba with user names "test1" and "Test2". (Please note the capital letter in Test2). Created two shares in /srv/samba/shares "test1" and "Test2". The permissions of the shares are as below. drwx------ 2 test1 users 4096 2009-12-11 12:42 test1 drwx------

Hello list, this is the dialplan : <snip> exten => s,n,Dial(SIP/test1&SIP/test2,,t) <snip> exten => 10,1,Dial(SIP/test1) exten => 20,1,Dial(SIP/test2) So there is an incoming call that rings SIPaccounts test1 and test2. Account test1 answers and wants to transfer the call to test2. Transfer is : #20 This is what the CLI shows : [Jul 2 10:55:30] -- Executing [20

Hi all, sorry to post to both lists, but I'm running into an issue where clang-generated debug info is deemed to be invalid by LLVM tools (throws an assertion error in both llc and mcjit), and I'm not sure what the proper resolution is. Here's a test case; I last tested it on revision r210953: $ cat test1.cpp #include "test.h" test::Test<int> foo1() { return

Hi, Say I have two packages, test1 and test2, that both define the generic method train (identical definition), and each has a specific train method for a different S4 object (foo and bar, resp.) I want to be able to call train(foo, x, y) and train(bar, x, y), which doesn't work since test2 masks test1, as seen below. The two solutions I can think of are to a) prefix train,

I have a test case where lld-5.0 fails to detect an undefined symbol (this bug also happens with clang/lld 4.0). I haven't narrowed down exactly all the circumstances when this can occur, but in this case it was for a virtual method in a class defined in a shared library. If I build the executable with the raw object files, the linker notices the missing method (see test1 vs test2). This

Hello everyone, I have a data frame (tt), see below (I only show 2 genes, actually I have a lot): group gene1 gene2 Control 28.9776 9.9355 Control 28.9499 10.0997 Control 29.5468 14.2995 Control 29.5246 13.9561 Test1 29.1864 9.7718 Test1 29.2048 10.0388 Test1 34.9563 11.9509 Test1 34.9464 11.8909 Test2 36.9566 14.5316 Test2 37.1309 14.5188 Test2 36.1017

Hello R users, I'd like to ask a question about how to add a new column. So, below is my situation.

Hi All, I came across a FileCheck failure I don't understand why. The example code below: void test1() { ... code ... // CHECK-LABEL: @test1 // CHECK: void @llvm.memcpy.p0i8.p0i8.i32 - (1) } void dummy() { // make (1) match ... code ... // CHECK-LABEL: @dummy } void test2() { ... code ... // CHECK-LABEL: @test2 //

Hi all, I am trying to create a list of all variable/value combinations in environment(). When a function with unset arguments is called, the method I have been using fails with a "missing argument" error. However it should be possible to simply skip these missing objects in the generation of the list? Could anyone recommend me a better way (that does not use a slow

In R 3.5.0 using the `encoding' argument of source() prevents loading files from the internet; without the `encoding' argument files can be loaded from the internet, but if they contain non-ascii characters, these are not correctly displayed under MS-Windows (but they are correctly displayed under GNU/Linux). With R 3.4.{2,3,4} there is no such problem: using `encoding' the files are

Is it expected that attributes set on a LGLSXP created by ScalarLogical will apply to all future objects created by ScalarLogical as well? For example: the 'test1' function below returns FALSE and 'test2' returns FALSE with an attribute: library(inline) test1 <- cfunction(body = 'return ScalarLogical(0);') test2 <- cfunction(body = ' SEXP success =

R-help, I have a frame which I want to fill up conditioning to another data frame column. The one I want to fill up is as follows (basically an empty one): > test2 cm 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 3 3 3 3
