[R] Contour plots in R Studio

[Bert Gunter]

Well one would expect that you might find something useful by
searching the obvious, like

?contourplot

and following the links therein.

It also seems (to me, anyway) that you have made little effort to
understand how R works, its data structures, syntax, and so forth. So
please peruse "An Introduction to R" (or one of the many R tutorials
on the web) to learn about such basics before posting further if I am
correct in this assertion.

Cheers,
Bert
