after several tries and with help of lardman I finally managed to compile R.
R is a software package for statistical computing, more information you find here:
You can download a binary for testing on OZ/GPE 18.104.22.168 here:
The ipk contains the basic R binary, the documentation, the reccomended modules and the gstat module. After installation you will have 70MB less space on your Z. Therefore I recommend to install it on SD or CF. ipkg-link does not work for big packages like R (there is an assigned entry in the bugtracker on this topic already). An easy solution is to set an symbolic link from the installation directory to /usr/local like this:
ln -s /media/card/packages/usr/local /usr/local
Unfortunately opening a graphics window will NOT work with the tiny libx11 included in OZ. You may want to replace the small libx11 with the full version. This will need 10MB of additional space on your root system (or on SD / CF). You will find version of libx11 that works with R at the above mentioned place.
If you need additional R-modules, you will have to compile them on your Z (see Dcoumentation on the R-homepage) and therefore need the native-sdk and several additional packages (see http://people.web.psi.ch/kosakowski/R-zaurus/README).
I tested the binary on my C760 and on qemu (with poky/OE), I have no idea if it works on other models ;-)
Happy computing, Georg
