Hello,

I very much enjoy rgl! But when converting the screen output to pdf using rgl.postscript I have encountered three problems:

(1) I don't seem to have control over font sizes and point sizes (of

added points) in the pdf output. I tried cex from "plot" but that
does not have an effect. Initially I got some plots where fonts and
especially points were far too small. But now I cannot reproduce this
any more and fonts and axis are way too thick. How do you control
font size, point size etc in the pdf output of rgl.postscript?

(2) I could not figure out if it is possible to prevent the

expressions entered for xlab, ylab and zlab to float around in the
plot. I would like them aligned with the labeled axis if that's
possible. Can I do that with rgl?

(3) I would also like to add a transparent sphere to some plots. I

did this by adding the next two lines to a plot. However, by adding
rgl.material(), also my next plots have the new updated properties I
only intended for the sphere. How can I re-set the rgl.material to
their defaults or how can I assign properties only for one object?

spheres3d(0,0,0,1, col= "yellow")

I am working under Win XP with R 2.4.1 and the most current version of rgl.

Thanks,

Kim
