yeah not sure how to do it. FastRWeb tell us:
" FastRWeb consists of several parts:
Webserver-to-R pipeline, consisting of either a thin CGI or a PHP client connecting to Rserve which sources and runs the R script. The CGI client is called Rcgi and is compiled as part of the package. The PHP client is part of Rserve in the clients section.
So Im on option 1: CGI. The client will be this binary which somehow needs to be
executed for each R script. I placed the Rcgi under cgi.bin directory and rename it
If I call directly:
http://localhost:9001/cgi-bin/R.cgi the browser returns:
Error: no function or path specified.
I see under error log:
2013/02/19 18:39:53 [error] 2847#0: *56 open() "/opt/sdr/report/docroot/cgi-bin/R.cgi/foo.png" failed (20: Not a directory), client: 127.0.0.1, server: sdrrep, request: "GET /cgi-bin/R.cgi/foo.png?n=100 HTTP/1.1", host: "localhost:9001"
