r-cran-rio binary package in Ubuntu Mantic amd64

 Streamlined data import and export by making assumptions that the
 user is probably willing to make: 'import()' and 'export()' determine
 the data structure from the file extension, reasonable defaults are
 used for data import and export (e.g., 'stringsAsFactors=FALSE'),
 web-based import is natively supported (including from SSL/HTTPS),
 compressed files can be read directly without explicit decompression,
 and fast import packages are used where appropriate. An additional
 convenience function, 'convert()', provides a simple method for
 converting between file types.
