3d Map with bars
Apologies in advance for the question. I am trying to draw a map of the US
as a surface plot so that I would be able to drop bars on the different
states (something like Uwe Ligges' scatterplot3d example 4). I am not sure
where to start looking for such a beast. If anyone has any pointers,
ideas, I will be grateful.
TIA,

3-D scatter plot laid over Surface plot
Hello,
I have created a Fitness surface (persp()), with data that was created
by a tp spline procedure. Now I would like to superimpose a set (XYZ) of
existing points (from two different treatments) onto this surface.
I didn't come across any function or command that is able to do this in R.
Could somebody please help me in finding a solution to this problem
Thank you
Peter

Excessive Swap with MSVC++ and Wine
Prompted by Jonathan Grant's article I've been playing with running the MSVC++
command line tools under Wine. In particular I'm trying to compile and link a
large DLL - about 4M in size.
The problem is the amount of memory used by link.exe. At the moment, with 256M
of real memory and 1G of swap I quickly run out. Under Windows2000, on the
same machine, the link takes a long time
