[R] CGI and RSPerl

[Nolwenn Le Meur]

Hi,

Does anybody try to write CGI script using RSPerl package ?

I am interested in RWeb but that doesn't really do what I want.
In fact I would like the user to load the file to analyze; then a R program
will treat the data ,display resulting graphs and save results in text
files.
I have test the following script by John Barnett without success.

#!/usr/lib/R/bin/R.bin --source
invisible(library(RSPerl));
foo <- .PerlExpr("use CGI;");
foo <- .PerlExpr("$q = new CGI; 1;");
a <- .PerlExpr("$q->param('a')");
cat(.PerlExpr("$q->header . $q->start_html . 'Hellooooo....';"),
    a,
    .PerlExpr("$q->end_html"));

I get the error:

premature end of script headers : /var/www/cgi-bin/test.cgi

Thanks to help,

Nolwenn
