Hello,
I feel I am drowning in a glass of water.
Consider the following snippet at the end of the email, where I
generated a set of {x,y,s=f(x,y)} values, i.e. a set of 2D coordinates +
a scalar on a circle.
Now, I can get a scatterplot in 3D, but

Using your data setup below and packaging into a dataframe.
require(rms)
ddf - datadist(xysf - as.data.frame(xys))
olsfit - ols(V3~rcs(V1,3)+rcs(V2,3), data=xysf)

Dear All,
I would like to plot a scalar (e.g. a temperature) on a non-rectangular
domain (or even better: I would simply like to be able to draw a contour
plot on an arbitrary 2D domain). I wonder if there is any tool to
achieve that with R. I did some online search in particular on the list

As to the domain of the function, at least in case (1), that should
arise from the collected data points in (x,y) if the sampling is
dense enough.
And that is precisely what you get from the perimeter function. The

Hi,
And thanks for helping. I am anyway a bit puzzled, since case (1) is not
only a matter of interpolation. Probably the point I did not make clear
(my fault) is that case (1) in my original email does not refer to an
irregular grid on a rectangular domain; the set of (x,y) coordinate
