Hello, all, Does anybody has ideas to call R from web page to do analysis and dynamically display generated graphics in the web page? There are couple packagas like Rweb and Rcgi. but seems the quality is not good enough and programming is too restrictive. I know insightful.com has a Statserver that can generate good graphics. (refer: http://www.insightful.com/products/statserver/default.asp), but it is not open source. Any suggestions are appreciated. Regards, William

Take a look at the RSessionDA (http://www.analytics.washington.edu/Zope/projects/RSessionDA/) for Zope (http://www.zope.org). -G > -----Original Message----- > From: LIANHE SHAO [mailto:lshao2@jhmi.edu] > Sent: Friday, November 21, 2003 11:34 AM > To: bioconductor@stat.math.ethz.ch > Subject: [BioC] how to display graphics on the web? > > > Hello, all, > > Does anybody has ideas to call R from web page to do > analysis and dynamically display generated graphics > in the web page? > There are couple packagas like Rweb and Rcgi. but > seems the quality is not good enough and programming > is too restrictive. > > I know insightful.com has a Statserver that can > generate good graphics.

Dear William, I think it is not that hard. We have (actually, Juanma Vaquerizas has) prepared a cgi that works as a web interface to limma and a few kluges of us; you can give it a try at http://dnmad.bioinfo.cnio.es. The basic skeleton is Perl, and we we use the CGIwithR package (http://cran.r-project.org/src/contrib/PACKAGES.html#CGIwithR), by David Firth, to communicate between R and Perl; figures are displayed as png (we are satisfied with the png's quality). We also tried RSessionDA (see Greg's message), but we had a harder time getting it to work, so we opted for the solution above. Please note that this is just a beta version! (and it is running from a dual Xeon machine, so please, be gentle). If you can wait a little bit, we are writing a note for R news, and we will provide all details there, and downloadable code from our webpages. Best, R.

I use a combination of Perl, Apache, R and Xvfb. Apache is the web server. I write cgi scripts in Perl. The Perl code opens pipes to R as usual: open (R, "| R"); I use the R command jpeg() to produce graphs as jpeg files. As I am using Xvfb, a virtual X server, then R uses this to generate the images instead of using the real X server, so there are no security risks (that I can think of). Hey presto, everything works. -----Original Message----- From: LIANHE SHAO [mailto:lshao2@jhmi.edu] Sent: 21 November 2003 16:34 To: bioconductor@stat.math.ethz.ch Subject: [BioC] how to display graphics on the web?
