Greetings all!
I'm wanting to plot contours of a function, and I don't
want to evaluate it at a dense grid of points (i.e. I don't
want a huge array of values).
Say I have a vector of x-values such as x <- 0.1*c(1:10),
and the same for y <- 0.1*(0:10).
I then evaluate a 10*10 matrix z of values of z = f(x,y).
so I can then do
CL <- contourLines(x,y,z)
and get a list of
