[R] running R from Perl

[Andrew Perrin]

I'm certain it's possible, although I haven't tried it myself. The two
possibilities I can think of off the top of my head are:

1.) Use R's ability to read and write to/from sockets. Perl is happy to
open sockets (perldoc Socket), so you should be able to send data back and
forth that way. In R, see:

> apropos('socket')
[1]
"close.socket" "make.socket"  "print.socket" "read.socket"  "write.socket"


2.) Send the data to a temporary file from perl, then launch R with a
batch script to read the data and write the plot to a temporary file, then
read the temporary file from perl.

Hope this helps.
