Hi everyone, Sorry about last message, the send key slipped. Does anybody know about ternary (tertiary?) plotting functions for R - they're triangular things used much beloved by chemists for plotting compositional data. Regards, David. ********************************************************** ** Dr. David Lucy ** ** Centre for Forensic Statistics and Legal Reasoning ** ** Department of Mathematics and Statistics ** ** The University of Edinburgh ** ** James Clerk Maxwell Building ** ** King's Buildings ** ** Mayfield Road ** ** Edinburgh ** ** EH9 3JZ ** ** ** ** tel: 0131 650 5057 ** ** e-mail: dlucy at maths.ed.ac.uk ** ********************************************************** -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)

David, Greetings from the west coast! Here is my ternary or triangular diagram function. Geologists use them a lot too. Usage is as follows # some random data in thre variables c1<- runif(5, 10, 20) c2<- runif(5, 1, 5) c3 <- runif(5, 15, 25) # basic plot tri(c1,c2,c3) # plot with different symbols and a grid tri(c1,c2,c3, symb=7, grid=T) Hope this helps, Colin.> Does anybody know about ternary (tertiary?) plotting functions for R - > they're triangular things used much beloved by chemists for plotting > compositional data.-- Colin Farrow Computing Service, University of Glasgow, Glasgow G12 8QQ Tel: 0141 330 4862, c.farrow at compserv.gla.ac.uk -------------- next part -------------- An embedded and charset-unspecified text was scrubbed...
