Hi,
I got the same result with David's version, but defining the *lim values
prior to the function actually made it work. I also renamed the points pts
so it wouldn't matter whether it was pts1 or pts. The new code is:
data.frame(x = seq(-4, 0, 0.5), y = seq(0, 40, 5))-> df
expand.grid(x = df$x

I do not. The code that works for me is:
wireframe(z ~ y*x, gridd, drape = TRUE, colorkey= T
Hi David,
Thanks for the suggestion - I changed pts1 to pts, but I still got the same
error as before. Do you know what else I'm doing wrong?
Thanks,

PS. New code is:

That's true, and I think it would be easy enough to have a flag to

Hrm. I have to admit, I don't entirely understand how to use the scaling,
and that seems like a lot of unneeded extra code. It is what it is, though.
The documentation about scaling is somewhat obtuse. Do you have a clear
explanation of what it is and how to use it in this instance? Perhaps e

A quick question. I'm trying to plot a surface from a fitted model
along with the original points, as in the following example:
df<-data.frame(expand.grid(100*runif(1:100), 100*runif(1:100)))
df$Var3<-rnorm(length(df$Var1), mean=df$Var1*df$Var2, sd=10)
