about latex and R

Hello. I installed Suse 9.2. I am not able to install latex properly because I do not find tetex and telatex either in the installation cds or through the ftp. Moreover I need to use a statistical software called R; although I downloaded the rpm precisely for the 9.2 version, there is an error in the compilation because a library called libg2c is missing! How can I install latex and R? Any help will be appreciated. Stefano
