Dear Prof. Ripley,
Thank you for your confirmation and explanation, I understand the reason
for cleaning things up to save memory. However, it was very convenient
to have this feature in earlier versions of R. It would be really
helpful to have an additional option to R CMD check, e.g.

Am I misunderstanding rawConnections here or are

but readBin does not position the read pointer past

Dear list,
Is it possible to update or reassign '.self' with an image of '.self'
(e.g. a locally stored .Rda file) from within a method?
I know that this might sound akward, but here's the use case:

Hi all,
Can help me understand why write.csv manipulates a call object instead
of simply calling write.table with modified arguments? I would have
written write.csv as:

Call <- match.call(expand.dots = TRUE)
