History: PluginR

R is a free software environment for statistical computing and graphics. It compiles and runs on a wide variety of UNIX platforms, Windows and MacOS

This plugin, which can be obtained from [http://mods.tiki.org|Mods], allows to execute R commands in a wiki page and show the results in that page also. Data for the program can be dynamically referenced from tracker item attachments. 
See some pre-configured example at teh documentation page (link below)
