I am a total newbie at R but experienced with computers. If this is not the
right forum for this question, please let me know one that is. I searched in
the R manuals in the Help section, the Nabble help and Rseek but no luck.

I am trying to install the package gcl on my recently installed R 2.8.1

I searched on cran for the windows version and found a zip file for the
package

In RGui, I ran Packages|Install Package(s) from local zip files
This ran without any error messages

When I look in the 'library' directory of my R installation I see a
subdirectory named 'gcl' with subdirectories
'demo','man','R'

I try to run gcldemo.r in the Demo directory and get the following messages:

> source("C:\\R-2.8.1\\library\\gcl\\demo\\gcldemo.r")

Error in eval.with.vis(expr, envir, enclos) : 
  could not find function "gcl"

I have exited RGui and restarted it but still get same error

Any help appreciated.
