[Rd] replicate evaluates its second argument in wrong environment

[Gabor Grothendieck]

Currently replicate used within sapply within a function can fail
because it gets the environment for its second argument, which is
currently hard coded to be the parent frame, wrong.  See this link for
a full example of how it goes wrong and how it could be made to work
if it were possible to pass an envir argument to it.
