Hi Michael,
can you please

just for the convenience of your readers
- use R-help. This is really a question about R.

I took the opportunity to run aspell over all the help pages, so this
turned into a few dozen small corrections.

Try issuing the command:
options(keep.source = FALSE)
prior to running the code you displayed to force the actual source,
rather than the source attribute, to be displayed by print when printing
functions.

Ok, so be it:
We have seen that both apropos() and find()
have used `some' non-standard evaluation up to R 2.4.1
which gave quite incosistent behavior.
Getting rid of non-standard evaluation get's rid of all
inconsistencies but of course is not back-compatible either.
I'll do this.

Dear All,
This is not really a bug report, but rather a change wish to the Base R
behaviour
on some functions when applying them to character strings vectors/matrices.
Actually in R, we can do thinks

You haven't told us what you consider to be the bug here. Note that the
help page for update says
'update' will update and (by default) re-fit a model. It does this
by extracting the call stored in the object, updating the call and
(by default) evaluating that call. Sometimes
Thanks Peter. I see the dilemma. It is serious in my view, though,
even if I can't see an elegant way round it.
I guess the only possibilities are
1. Only keep the source in printing or, much more seriously, dumping, if
the source attribute parses to an object structually identical to the
15 matches
