[R] OT: Any reason why one of my computers is so slow?

This is not a criticism of R, but R runs much slower on one of my machines than it does on the others, so something is wrong with that machine, but I don't know where to look for a remedy. Here are the details: I have a 32-bit win xp machine running at 2.66Ghz and a 64-bit win 7 machine runnin

Hello, Try x <- "(O, O, O, H, L, O, O, O, O)" strsplit(gsub("\\(|\\)|[[:blank:]]", "", x), ",") Note that the result is a list, not a vector. You can then use `[[` or unlist(). Hope this helps, Rui Barradas Em 28-06-2012 11:42, Jessy escreveu: Dear all, I have a vector of length 1 but

You can use gsub() to eliminate the parentheses, and strsplit() to separate the elements. Sarah On Thursday, June 28, 2012, Jessy wrote: > Dear all, > > I have a vector of length 1 but within this vector there are 9 elements > > vectorNOcorrection > [1] "(O, O, O, H, L, O, O, O, O)" > can someon

Re: [R] Make a reference?

Hi, I don't see how this is an R question. You add references in whatever way is appropriate for your word processor or document preparation method and your bibliographic software. R is neither of those things, though citation() is rather underused. Sarah On Wednesday, June 27, 2012, quantum wro

Clearly you're right - and polite... as always I asked the question because I wanted to avoid 'paste(x, collapse="/")' and 'do.call(file.path, as.list(x))' because it's less efficient than 'file.path()' and '?file.path()' explicitly recommends *not* using 'paste()' for putting together file pa
