You can run R scripts in batch mode and direct output to file. That would be by far the simplest. Or, you could explore RSOAP to run R as a web service which allows creation of R sessions which persist (i.e. the binary data objects stay around) between requests from another application (which could include a Perl script using Perl's soap libraries). A third option is the Rserve system which allows connection to R sessions using TCP/IP from other software applications. See the R helpfile on the BATCH command (?BATCH) and/or http:ess.r-project.org/Zope/projects/RSOAP/ and/or http://stats.math.uni-augsburg.de/Rserve/ HTH, -Eric > Is it possible ? > Where can I get information to do that?
