[R] Fw: Creating a barplot--advice needed

[Thomas L Jones, PhD]

Subject: Creating a barplot--advice needed


> Advice needed: I am preparing a computer program to do a barchart. Advice 
> needed: Should I learn the lattice package, or try to? As a 
> non-statistician, much of the terminology is unfamiliar to me. "grouping 
> variable," "object of class trellis," etc. Or, is there a more easily 
> learned way to do it? It is a simple, vanilla-flavored barplot. Each of 
> the bars has the same width. I knos how to create the barplot using a 
> speadsheet program (MS Excel or equivalent), but I do not know how to put 
> the barplot on  top of a R graphics windows. I have a PhD in Computer 
> Science, but am no statistician.
