[R] Installing rgl

[aoife]

Hey guys,I'm working with R version 2.14.1 (2011-12-22) on a unix machine and
I'm having a similar problem. I have a matrix and i want to do a simple
correspondance analysis. I tried to install the ca package i get this error:

> library(ca)
Loading required package: rgl
Warning messages:
1: In rgl.init(initValue) : RGL: no suitable visual available
2: In fun(libname, pkgname) : error in rgl_init
> 

so then i downloaded rgl, at the end of the installation process for rgl it
says:

Warning messages:
1: In rgl.init(initValue) : RGL: no suitable visual available
2: In fun(libname, pkgname) : error in rgl_init


and when you look in the library for rgl you get:
> library(rgl)
> 


Would anyone know (in simple language, i'm a biologist, not a statistician
:( ) either how to fix this, or an alternative package that will do a simple
correpondance analysis on a matrix?

Many thanks
Aoife
