Hi R help,
What is the best way to plots surfaces in 3 dimensions?
That depends a lot on what the surface is like, and what you are
intending to do with the plot. Possible functions include persp,
contour, wireframe, persp3d, etc.
I also have the following availability problem with "plot3d" and "scatterplot3d", and
"wireframe":
install.packages("scatterplot3d")
Warning: unable to access index for repository
http://cran.ch.r-project.org/bin/macosx/leopard/contrib/2.10
Warning message:

package ‘scatterplot3d’ is not available
This is likely related to the temporary power problems in Vienna. Some
mirrors were also affected by them, because of dependencies on the CRAN
master.
install.packages("plot3d")

I don't know of a plot3d package. There's a plot3d function in rgl, and
a plot3D function in compositions.
wireframe(volcano, shade = TRUE,
+ aspect = c(61/87, 0.4),
+ light.source = c(10,0,10))
Error: could not find function "wireframe"
The wireframe function is in the lattice package, so you need
library(lattice)
first. (The persp3d function is in rgl.)
