Oops, Sorry, did not reply-all: Thanks for the reply Simon,
I have a follow-up question: So after I run the first code you suggested on a computer, the shared object will use the Fortran run-time included in R. Does this code change the shared object itself? Meaning if I send this object to yet another computer and run it, will it know to link to the Fortran included in R? Thanks! -Best, Xiao On Thu, May 23, 2013 at 5:06 PM, Xiao He <praguewaterme...@gmail.com> wrote: > Thanks for the reply Simon, > > I have a follow-up question: > > So after I run the first code you suggested on a computer, the shared > object will use the Fortran run-time included in R.
