[R] Re ad in a file - produce independent vectors

[Gabor Grothendieck]

Just read them in as whole lines and then split them
giving a list of vectors.  See ?readLines and ?strsplit

Lines <- readLines("meat.txt")
strsplit(Lines, " +")

This can also be done using strapply in gsubfn which
extracts words rather than splitting on delimiters:

library(gsubfn)
strapply(Lines, "\\w+")

More info on gsubfn is at http://gsubfn.googlecode.com
