Jari, thanks so much for the advice. I followed your instruction and could install rgl too. It's really fun playing with it.
I have written up a more detailed instruction, hopefully this will help less experienced R users. 1) go to apple.com, download Developer Tools and X11. You need to sign up as an ADC member if you haven't yet. Install both. 2) go to http://www.rna.nl/ii.html, get i-installer, install it. Run i-installer, find the libpng package and install it. 3) Download the source of rgl 4) At the terminal, do "R CMD INSTALL rgl". I did this in super use mode, I am not sure if I needed to though. If this is successful, you will see /Library/Frameworks/R.framework/Versions/2.0.0/Resources/library/rgl/libs/rg l.so being created Saiwing On 11/8/04 1:38 AM, "Jari Oksanen" <[EMAIL PROTECTED]> wrote: > On Sun, 2004-11-07 at 02:54, Saiwing Yeung wrote: > >> It seems like a number of people on this list can install rgl but have >> problem loading it.
