The R Project for Statistical Computing is gaining ground world wide after I adopted it for all my analyses & plotting ;-). And imagine I had plotted in R without using Hadley's wonderful ggplot2 package!

http://cran.r-project.org/web/packages/ggplot2/

I find it as difficult to learn then everything else in R, but I'm plodding on. I just found is that ggplot2 has been updated. What caught my eye was that boxplots now can be notched, and then these interesting "guides" which allow more control over the appearance of the output. Thanks!
