• Complete installer

• Bundled integrated editor (Windows: Tinn-R, Unix: XEmacs+ESS)

• Standard set of high-quality extension packages pre-installed 

• Complete CRAN archive included (850+ packages)

• Compilers, tools and libraries necessary for developing add-on packages

• Package version and location information displayed when loaded
