R help - Sep 2004 - Interface between R and Perl

Hi,

I have made a GUI in PerlTk and I would use R within perl.
I actually try to install RSPerl but I have some problems during the compilation

In order to call R from perl I use actually an other system based on the OPEN
command in perl.
It works fine but when I tried to call the fonction plot() of R from perl the
plot do not appears and a file named plot.ps is generated.
Unfortunalelly, my plot is dynamic (I also use the identify() command) so I
can't integrate this plot as an jpeg image for example.

My question is :
Is there a solution to call the plot() and identify() R commands from perl in
order to have a dynamic plot ??
can RSPerl do this or not ??
If it can I will spend more time to install it.... but it looks hard

Thank you very much and excuse me for my english :-)

Hi,

I've installed rgl package through R CMD INSTALL on a Debian-Sarge machine
(PIV) without any compiling error (see attached file), but when trying to
load this package within R (and also Rcmdr library) I get:
> library(rgl)
RGL: GLX extension missing on server
Error in firstlib(which.lib.loc, package) :
error rgl_init
error in library(rgl) : .First.lib failed
Segmentation fault

Same failure problem if I use the apt option (apt-get install r-cran-gl).
I've searched through the R mail archives but couldn't find or
understand
the answer for this problem.

Thanks in advance!

I don't think RSPerl can do this  from within perl, but others would 
know better than I.  Have you considered using tcltk for R?  You could 
recreate the GUI there, if the GUI is that is the use of perl in your 
application.
