Actually I must correct myself, the named pipe will work (thanks Reid!).
Also the suggestion to mix R commands and data should work, but I think I prefer the
named pipe. The datafile will be huge in my case like GB, so that is the reason I do
not want to use temporary files.
Thanks to everybody!

Thanks for the answer!
However what I would like to ba able to do is something like:
perl -e 'print "1 2\n\2 2\n";' | R --silent commandFile
and commandFile would contain something like:
t<-read.table(file("t"), sep=" ")
print(t*2)
This would need read.table to get the original stdin() and the commands to be read
from a file.
The idea with the named pipe does not work either for the same reasons.
Thanks again,
Alberto
