Hello,
I'm *guessing* that this is more likely an issue of R than of org-mode.
Have you tried tangling the code and simply running the scripts through R?
Essentially, the as.matrix function call is returning a character
matrix, which could mean your object 'alldata' has some factors instead
of numeric columns.
R 2.7.1 is, by R standards, ancient, so it would not surprise me a bit
if the differences were because of that old version.
Unless you can show that this is somehow org-mode related, I'd construct
a reproducible example and ask R-help. In any case, reproducible
example will help in solving the problem.
Good luck!
