[R] 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 -- ----------------------------------------------------- William C.

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... -Ista On Thu, Oct 21, 2010 at 6:46 PM, William C.
