As you can see from the minimal example below, the parameter "lwd" does not solve this problem. What can I do to make the plot symbol thicker?

Marius,
Jannis's reference is good, but wireframe needs a bit more
tweaking than xyplot. You need to edit panel.3dscatter (very
slightly). Find this code:
lpoints(x = m[1, ord], y = m[2, ord], col = col.point[ord],
pch = pch[ord], cex = cex[ord])
and modify it to:
lpoints(x = m[1, ord], y = m[2, ord], col = col.point[ord],
pch = pch[ord], cex = cex[ord], ...)
Save the modified code as mypanel.3dscatter and set its environment
with
environment(mypanel.3dscatter) <- environment(panel.3dscatter)
Then replace panel.3dscatter with mypanel.3dscatter in your
code and replace your 'lwd=10' with 'lex=10'.
If Deepayan is reading this and doesn't have a better idea, he
might perhaps make the change permanent.
