Here's a related question: Do any of the mentioned R-web interfaces (Rweb, R-Online, CGIwithR, RSPerl) support reusing the same R process, eliminating the startup overhead? This would be useful to me as well.
Currently I use such a method on my computing cluster: All 40 compute nodes run an R process/compute server that listens at a socket for any connection and subsequent commands from another computer. When the master process disconnects, the R processes go back to listening at the socket. Connecting to the R compute servers this way takes < 2 milliseconds rather than the typical ~2 second R startup time. Thanks for any tips. -Frank -----Original Message----- From: Christian Lederer [mailto:[EMAIL PROTECTED] Sent: Thursday, May 06, 2004 10:04 AM To: [EMAIL PROTECTED] Subject: Re: [R] cgi/servlets/httpd in R Hi, if found that the easiest way for me doing CGI with R was using the RSPerl package. So i could do all the CGI related things in Perl and call R functions from Perl to do the statistics. You can get RSPerl from http://www.omegahat.org. If loading the data each time gives a performance problem, i guess that you could use RSPerl together with fastcgi, so the R initialization and loading the data would happen only once. If you try this, i would be very interrested in your experiences. The RSPerl package is somewhat outdated, but it worked well together with R 1.6.0 (i didn't try newer versions).
