invoking R scripts from a linux shell ?
Hello,
I have written perl programs that extract data from a
text file, process them, and create other text files,
which I'd like to apply some statistics too (for
example with R).
I'd like to do it all in once , with a single script.
I'm not familiar with R, I'd like to know if this task
could be accomplished by creating a linux shells that
launches the perl scripts and then
