R

R is currently used by the Systems Biology Research Tool's Correlation Estimation process. This is accomplished by using a Java/R interface (JRI). To use this process, both R and JRI must be installed on your system.

Installing R

Instructions for downloading and installing R in Windows, Macintosh, and Linux can be found on R's main page and in the R FAQ.

Installing JRI

Instructions for downloading and compiling JRI can be found on its main page. The java archive (JRI.jar) and the shared object file (libjri.so), or the dynamic-link library (jri.dll), must be placed in the System Biology Research Tool's lib directory. In Linux (at least), the environment variable R_HOME must be set to its appropriate value as well. This could be done in bash, for example, by executing the following command: R_HOME=/usr/lib/R ; export R_HOME
