rggobi is an R package that provides an easy interface with GGobi.
install.packages("rggobi")rggobi and all its requirements (including rggobi) you can run source("http://www.ggobi.org/downloads/install.r").Note for Linux users: you will need to set PKG_CONFIG_PATH to PREFIX/lib/pkgconfig where PREFIX is the prefix GGobi was configured to use. By default this is /usr/local, so PKG_CONFIG_PATH would need to be set to /usr/local/pkgconfig.
The first place to start is to read the ggobi help page, ?ggobi. It will also be useful to read the included introductory vignette (and soon to be R news article): introduction to rggobi
