Hi, I need to do some simple coordinate transforms between cartesian, cylindrical and spherical coordinates. I can't find any built in functions or packages to do this, is this because they do not exist? Obviously I can write my own code, but don't want to re-invent the wheel if I can avoid it. Cheers, Matt

Try RSiteSearch("spherical coordinates") to find them. Duncan Murdoch
