[R] strsplit and regexp

[Gabor Grothendieck]

Try this:

> library(gsubfn)
> strapply(x, "[0-9]+| +[^ ]+ *")[[1]]
[1] "2"       " Value " "34"      " a-c "   "45"      " t"

which keeps the spaces around the non-numeric entries as in
your example; however, if keeping the spaces is not important
then its even easier:

> strsplit(x, " ")[[1]]
[1] "2"     "Value" "34"    "a-c"   "45"    "t"
