Assuming that the obvious solution (splitting up the function into pieces)
doesn't work you can use

   options(keep.source=FALSE)

to tell R not to store the source text in addition to the parsed code. The
only disadvantage of this is that when you list the function source inside
R there aren't any comments, but you don't want to do this with 100 pages
of code anyway.
