R help - Oct 2010 - Ordination plot option missing from PCA dialog

Hello,

I am trying to learn how to do PCA. I found a tutorial online, but what 
I'm seeing in my installation does not match what is in the tutorial. 
Specifically, if I select Statistics:Dimensional Analysis: 
Principal-components analysis, the dialog I am presented with does not 
include an option to create an ordination plot.

My question is why not? Is this a problem with my data set, local 
computer configuration (I am having trouble with the rgl package), or 
something else?

I have R-2.11.1 installed on SuSE SLES 10.1.

thanks,
Bill

Hi Bill,
R does not have a standard menu-driven interface, but rather several
contributed interfaces including Rcommander, RKward, Deducer, and
others. In order or anyone on this list to help you we are going to
need to know which one you're using...
