Subject: Re: [R] Ternary plot and filled contour
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:
http://ggtern.com/case-study-zirconia-alumina-silica/
Hope you find it of value.
Best Regards,
Nicholas Hamilton

Dear R-Users, I'd like to have some tips for a ternaryplot ("vcd").
I have this dataframe:
a<- c (0.1, 0.5, 0.5, 0.6, 0.2, 0, 0, 0.004166667, 0.45) b<- c
(0.75,0.5,0,0.1,0.2,0.951612903,0.918103448,0.7875,0.45) c<- c
(0.15,0,0.5,0.3,0.6,0.048387097,0.081896552,0.208333333,0.1) d<- c
(500,2324.90,2551.44,1244.50, 551.22,-644.20,-377.17,-100, 2493.04) df<-
data.frame (a, b, c, d)
and I'm building a ternary plot:
ternaryplot(df[,1:3], df$d)
How can I map the continue variable "d", obtaining a result similar to this
one? [see the link]
