Bert,
Thanks for the tip. Yes, strsplit works, and works fast! For me,
white-space tokenization means splitting at the white spaces, so the
"^" and the outermost square brackets should/can be omitted.

You might want to look at function read.csv.ffdf from package ff which can read

on disk resp. in the file-system-cache. Once you subscript part of it, you get
