Dear R experts,
On explanation of persp() parameters the last item is:
...: additional graphical parameters (see `par').
However, setting the `tcl' parameter has no any effect. I guess that axes are added to persp() in somewhat freakish way, and have nothing in common with axis() function.
I found the very useful trans3d() function in persp() help page, and I'd like to use it with persp() + axis(), but I didn't find how to draw axis() in arbitrary place & direction :(
So, I want to customize axes in persp(). Could anybody help me solve this problem? Thanks a lot!
It's not that easy, since persp() is quite special and its code is "hard coded" in C. axis() works "only" for the 2D R graphics.
You might want to look at wireframe() in package "lattice".
