Try ternaryplot in the vcd package -----Original Message----- From: Richard A. O'Keefe [mailto:[EMAIL PROTECTED] Sent: Tuesday, 15 July 2003 11:55 AM To: [EMAIL PROTECTED] Subject: [R] R, geochemistry, ternary diagrams
I'm in e-mail contact with a geochemist who maintains a well regarded geochemistry web site. He's drawing diagrams either with a Turbo Pascal program running in a DOS window or with Excel. I'm trying to persuade him that R would be a better choice. Something he's particularly keen on is ternary diagrams. I think he is talking about ternary phase diagrams, and if so, it looks as though it should be doable in R, but I don't know enough about the lower levels of R graphics to do it myself (yet). Looking at his speed and volume requirements, R can handle them easily, even on a machine about 1/4 of the speed he has in mind. Are there enough geochemists using R already that he'd find like-minded people to discuss technical issues with if he _did_ switch to R? Is there a package somewhere already that does ternary and other geochemistry diagrams? ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
