Thanks in advance! > I had a quick look at this issue, and indeed, rgl failed to load in my system (MacOS X 10.3.6, R 2.0.0) with various error messages. It seems to me that the binary packages at CRAN were incompatible (g++ is notorious for version changes incompatibilities). The solution was to use source packages and compile locally. For this you need to have a compiler installed. The compiler comes with MacOS X 10.3.* installation cd/dvd, but you have to install their "Developer Tools" separately.
One of the early error messages was that libpng was missing. When installing from source, rgl was configured without png support, and this message disappeared. However, CRAN binaries failed even after installing png libraries, but now with other error messages. I got my libpng with the help of http://www.rna.nl/ii.html (that you need anyway). It may be that you have to start X11 separately before calling library(rgl), but this was not necessary in my later attempts. Summary: install from source package. Optionally, you may install libpng as well. cheers, jari oksanen -- Jari Oksanen -- Dept Biology, Univ Oulu, 90014 Oulu, Finland email [EMAIL PROTECTED], homepage http://cc.oulu.fi/~jarioksa/ ______________________________________________ [EMAIL PROTECTED] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
