[R] Limit on Function Size

[ripley@stats.ox.ac.uk]

You have probably hit an old limit which was not checked until 1.6.0 (to
be).  The limit is on the amount of text source kept with a function, and
is 128Kb as I recall (sounds about right).  This does not apply to
functions read in from packages (by default).

Use options(keep.source=FALSE), or write shorter functions!

Why not use source(...)?
