More philosophically, the dput output is more idiomatically appropriate for

Luis,
C_rnorm is a symbol but it's not exported. This means that you *can* do
this by using stats:::C_rnorm.
That said, it's not exported, which means that it's not supported to do
this. So your package likely would not be allowed on CRAN, for example.

You just need an available.packages matrix which reflects the reality you

these, but switchr allows you to build repositories off of many things

Hi all,
I can confirm this occurs for me as well.
The one thing that comes to mind is that there are certain larger
expressions that contain calls to return which we absolutely don't want to
be an error, e.g

return(TRUE)

Hi Dario,
My switchr package is designed specifically to do what you're describing,
and does support excluding site libraries. So clearly I agree it would be
useful, but also, it does go against the "concept" of site libraries
somewhat.
I agree it would be a useful addition with the default to in
Of course you can, but the ability to do something via R code and the

convenience, IMO.

Out of my naive curiosity, what arguments are you hoping a method for t()
will take?
I mean honestly an argument could be made that all S3 generics should take
I don't think its an overwhelmingly compelling one, but I d see some
merit to it given what an s3 generic is at its core.

Hi all,
so I've known for a while that NROW(NULL) gives 0, where nrow(NULL) gives
an error, so I naively expected NCOL to do the same.
Of course, it does not, and is documented* (more on this in a bit) as not
doing so. For those reading without the documentation open, it gives 1.

Abby,
Vectors do have an internal mechanism for knowing that they are sorted via
ALTREP (it was one of 2 core motivating features for 'smart vectors' the
other being knowledge about presence of NAs).
Currently I don't think we expose it at the R level, though it is part of
the official C API. I d
Hi all,
I was asked a question about why browser() was behaving a specific way, and
it turned out that it was being called in a script (rather than in a
function).
Putting aside the design considerations that lead to that, the behavior is
actually a bit puzzling, and so far as I have been able to

Hi Antoine,
I would say this is the correct behavior. S3 dispatch is solely (so far as
I know?) concerned with the "actual classes" on the object. This is because
S3 classes act as labels that inform dispatch what, and in what order,
methods should be applied. You took the function class (ie label

Hi Henrik,
A couple of things. Firstly, so far asI have ever heard, it's valid that a
package have hard dependencies in its tests for packages listed only in
Suggests. In fact, that is one of the stated purposes of Suggests. An
argument could be made, I suppose, that the base packages should be u

Hi Adrian,
I had the same thought as Luke. It is possible that you can develop an
ALTREP that carries around the tagging information you're looking for in a
way that is more persistent (in some cases) than R-level attributes and
more hidden than additional user-visible columns.

Hi Jim et al,
Just to hopefully add a bit to what Luke already answered, from what I am
recalling looking back at that bioconductor thread Elt methods are used in
places where there are hard implicit assumptions that no garbage collection
will occur (ie they are called on things that aren't PROTEC
