How change the size of persp() axis labels?

Hi,

I have been using the persp() function to plot species response surfaces
based on GAMs (using package mgcv).  Everything works fine, except that
I have a slight problem when it comes to producing a figure with
multiple (4 - 6) persp() plots on it.  The axis labels remain the same
size, no matter how large or small the plot is, causing some overlap
when the multiplot figure is produced.

Is there a way to reduce the size of the axis labels in persp() (either
for ticktypes="simple" or ticktypes="detailed")?

Ideally I would like to know how to reduce the size of the axis labels
when using ticktypes="detailed", and force persp() to plot only the min
and max value along each axis.  Is this possible?

R is running under Win2000.

I'm trying to remake R to use png on solaris.
I've installed the libpng and zlib packages,

	libpng-1.0.11-sol8-sparc-local
	zlib-1.1.3-sol8-sparc-local

and get this from ./configure

checking for png.h... (cached) yes
checking if libpng version >= 1.0.5... yes
checking for png_create_write_struct in -lpng... (cached) no
checking for XDR support... (cached) yes
checking for gzopen in -lz... (cached) yes
checking for zlib.h... (cached) yes
checking if zlib version >= 1.1.3... yes

after make and make check:  capabilities() still reports png FALSE.
I presume the problem is the "no" above, but I'm unclear what to do about it.
Any suggestions would be most welcome...for the record:

Looks like you forgot a:  

rm config.cache

before your

./configure

The truly paranoid can rm -r the R-1.x.y directory structure, 
and untar the source again, but the above should work fine.

Cheers

Yes, as Robert Gentleman suggested moments after my question was posted
this was a problem of not removing the config.cache file.  I did a
make clean and then  rm config.cache and then everything built smoothly.
The resulting png files are very convenient particularly in the pdflatex
environment, thanks to Guido Masarotto and Brian Ripley for this.

Um, no... 

PNG is a raster format. You'd likely be better off writing PDF
directly or using epstopdf on PostScript output.

Definitely better off with R's pdf() device unless you are really writing
raster images with image(), and possibly even then as pdftex handles
.pdf files better than .png ones.

Yes, I now agree.  I had had some trouble with postscript to pdf conversion
and had not tried the pdf() option, but it is now clear that either of
Peter's options are preferable to png() for what I wanted, which by the
way was pdflatex |ppower4 |acroread for projected slides.  Thanks to all
for the very helpful advice.

If it is for online presentations then there are some cases when png
is preferable to pdf: when you have scatter plots with LOTS of points
(several thousand, but that depends on your hardware), then acroread
can get very slow in rendering the figure (and some printers do run
out of memory when printing the PS) -> that's the only situation when
I prefer a bitmap to a vector graphic.

Best,

Another way to deal with graphics that are large ( e.g. images) is to save
them as postscript and then convert them to jpg format. I like using xv to
do this. The graphicx package with pdflatex supports this format for
figures.
