yes, well actually that was one of the first items I found in
my search. but on first pass I was confused, on second pass I
understood (sorta incorrectly) that it was about preserving source
when writing packages -- then I posted my question.

looking at it again I see the technique could be used to tidy r
scripts, but surly the first, the second paragraph or the rest of
the section was not written to aid programmers for script tidying?
"R treats function code loaded from packages and code entered by
users differently."...

Maybe it could go something like this "Your R scripts can be
sourced and dumped into a standard tidy format." (insert brief
explanation of keep.source, source and dump; which I think I grasp
but wouldn't try to explain)

Here's a script to tidy a file as argument $1

#!/bin/sh
R --vanilla <<EOF
     options(keep.source = FALSE)
     source("$1")
     dump(ls(all = TRUE), file = "${1}.tidy.R")
EOF


yes, works great, but as one with nearly zero r experience,
hoping to apply my other language experience to some R spaghetti,
http://cran.r-project.org/doc/manuals/R-exts.html#Tidying-R-code
did frighten me off, the first time.
