Forget what I said before, rectangular data works fine with contours, just need to get the x and y ordering correct firstly.
z<-matrix(data$z,length(y),length(x))
should be z<-matrix(data$z,length(x),length(y)) Sorry to bother you folks, I'm still learning this. I would say that R has good plotting facilities and quite fast too. - Tel -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-devel 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 !)
