When I click the Start R-Serve button to try to reproduce the steps
http://bio7.org/flash/rshellnew2.htm I get:
R-Server connection could not be established
probably the firewall is active->Please try again !
This sounds like Rserve is not installed on your Linux OS.
You have to install Rserve to use R with the Bio7 shell:
After the installation of R the path to the R (if not using the default path) application has to be
adjusted inside of Bio7 (“Preferences->Preferences Bio7″). In addition the path to the (add-on) packages install location has to be adjusted, too (“Preferences->Preferences Bio7->RServe Preferences”)."
