Hi all,
The help for delayedAssign suggests that you can use substitute to
access the expression associated with a promise, and the help for
substitute says: "If it is a promise object, i.e., a formal argument
to a function or explicitly created using ‘delayedAssign()’, the

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:
write.csv <- function (...) {
Call <- match.call(expand.dots = TRUE)
for (argname in c("append", "col.names", "sep", "de

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:
1) Ref Class Definition

Am I misunderstanding rawConnections here or are
rawConnections not working right yet? It looks
like I can use seek() to position the read pointer
but readBin does not position the read pointer past
what has just been read.

Hello, I was just tweaking the R build for the Homebrew package manager and I
thought it would be nice to enable bash completion. I noticed that
Debian-based systems install `/etc/bash_completion.d/R` but could not find a
source for this file in the `etc` folder of the R source.

Hi all,
What's the preferred way of capturing the expression representing the
contents of a function?
* body(write.csv) gives me a braced expression
* body(write.csv)[-1] gives me a mangled call
* as.list(body(write.csv)[-1]) gives me a list of calls
* as.expression(as.list(body(write.csv)[-1]))
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.

That doesn't agree with the documentation of is.language which implies
