Not a bug. .R is a `hidden' private directory for R's own use.
Have you been trespassing: `including stuff the user might have
installed' suggests you have?

Why: the targets of the links may well have changed? Remember that
R_HOME can change from invocation to invocation, and if there are
different R versions (even on different platforms) keeping anything is
completely inappropriate. You can't even delete just what you want to
replace, as .R might have been created by a later R version and put other
things in there.

Not so. Have you read the section on BUGS in the FAQ recently?
