[R] contour and persp

[Bill Simpson]

OK I think I have it, sorry to have bothered you:

x<-seq(1,2)
y<-seq(1,2)
z<-seq(1,4)
data<-data.frame(x,y,z)
x<-unique(data$x)
y<-unique(data$y)
z<-matrix(data$z,length(y),length(x))
contour(x,y,z,xlab="x", ylab="y")
persp(x,y,z, col="gray")

Now I just have to look back in my notes to find out how to make this work
for 1600 z values--currently R runs out of memory.

Bill
