[R] Ternary plot and filled contour

[Nicholas Hamilton]

Dear Francesco, 

I wanted to mention that I have just published on CRAN, a package for R, 
for the plotting of ternary diagrams. 

It is based off ggplot2, which is highly regarded, and, my website can be 
viewed at www.ggtern.com, including many examples, specifically including a 
case study at the following address:

Hope you find it of value. 

Best Regards,
