     `R.Version()' provides detailed information about the version of R
     running. 
     `R.version' is a variable (a `list') holding this information (and
     `version' is an `.Alias' to it for S compatibility), whereas
     `R.version.string' is simple `character' string, useful for
     plotting, etc.
