String manipulation
Dear all, I have following kind of character vector: Vec <- c("344426", "dwjjsgcj", "123sgdc", "aagha123", "sdh343asgh", "123jhd51") Now I want to split each element of this vector according to?numeric?and string element.

getting all pairwise combinations of elements in a character string
I'm able to do this as follows, but am wondering if anyone knows a simpler way which still avoids explicit loops? > (mystring <- letters[1:5]) [1] "a" "b" "c" "d" "e" > unlist(sapply(mystring[-length(mystring)], + function(x) paste(x,mystring[(grep(x,mystring)+1):length(mystring)],sep=""))) a1 a2 a3

[LLVMdev] Problem in llvm gcc back-end

For union assignment, llvm-backend seems generates assigning each member of

How to test views with Nested Resources and Partials
Hi everyone, I am relatively new to rspec and I am running into a wall in testing my views. I have a RESTful resource Contracts with a nested resource of Line_items. I am trying to figure out how to test the "edit" form of the Line_items. What complicates this is the nested routing and how to account for it, and that there is a partial form (_form.haml) that both the edit.haml and

Weird behaviour of tab characters in a string in R (vs Python)
Hello, I wanted to parse some information from a text, where fields are tab separated. When I copy the text into an R session (under emacs) like: mystring <- "field1 field2 field3" the tab character is replaced by a single space! For ex, if I type mystring, I get: "field1 field2 field3" The tabs have disappeared!!! I checked with Python that the text I copied was tab

[LLVMdev] Should the function operand flag 'sret' match the flag in function declaration?
I have these two instructions, first one inside some procedure, second one is an outside declaration. Code verification passes and it runs, but incorrectly. Every time I saw such situation coming from c++ compiler, attributes 'noalias sret' appear on both call and declaration. Does such situation make sense, or (as I guess it is) a bug in verifier? I think verifier should match at

Reading data entered within an R program
Dear R-helpers, I know of two ways to reading data within an R program, using textConnection and stdin (demo program below). I've Googled about and looked in several books for comparisons of the two approaches but haven't found anything. Are there any particular advantages or disadvantages to these two approaches? If you were teaching R beginners, which would you present? Thanks, Bob

Reading in tab (and space) delimited data within a script XXXX
Hello everyone, I use Bob Muenchen's approach for reading in "in-stream" (to use SAS parlance) delimited data within a script. This works great: mystring <- "id,workshop,gender,q1,q2,q3,q4 1,1,f,1,1,5,1 2,2,f,2,1,4,1 3,1,f,2,2,4,3 4,2, ,3,1, ,3 5,1,m,4,5,2,4 6,2,m,5,4,5,5 7,1,m,5,3,4,4 8,2,m,4,5,5,5" mydata <- read.table( textConnection(mystring),

Retrieving the context
Dear list, I have a general problem that I really don't know how to solve efficiently in R. Lets say we have a sequence of things, like for instance a string of words, that is stored in a file. We need all the words in a table format, so therefore we create an id for the word, that links the word to a file and the position of the word within the file, like: #In this case a very short file
