I'm curious to find out if there is an example of R code for optimization
of two variable function, with contraints, using lagrange multiplier
(using optim/nlm?). I have a problem that contains one discrete variable,
but need a simple problem/example to start with.

I haven't been able to find any examples and thought I should ask here
before I plunged into writing a few miles of R code.
