Yes, I think I see what you are going for (what I thought was (2)/(3)
is really just (3) in your scheme). Practically, I don't think it is
useful to differentiate between (1) and (2). To get (2)-like

Documentatio: typo in Writing R Extensions (PR#557)
Full_Name: stephen eglen
Version: 1.0.0
OS: Unix (OSF/1)
Submission from: (NULL) (129.215.238.26)
Hi,
in the documentation `Writing R Extensions', the section 3.6.1 (handling the
effects of garbage collection) has the following typo:
Protecting a SEXP pointer protexts ...
Should that be `protects'?

NULL == NULL
gives an error in R.
In both S+3 and S+5, it "works" by returning NULL or logical(0),
respectively.
As a consequence,
all(x == y)
returns TRUE in Splus, when x <- y <- NULL
but gives an error in R.
Do we have a good reason *not* to return logical(0) ?

Expected behavior from: all(c(NA, NA, NA) < NA, na.rm = TRUE)?
Hi all,
Came across this curious behavior in:
R version 2.5.0 Patched (2007-06-05 r41831)
A simplified example is:
> all(c(NA, NA, NA) > NA, na.rm = TRUE)
[1] TRUE
Is this expected by definition?
If one reduces this to individual comparisons, such as :
> NA > NA
[1] NA
> all(NA > NA)
[1] NA
> all(NA > NA, na.rm = TRUE)
[1] TRUE
the initial comparison on the 3

I suspect there may be more R users than you think that understand and
use vacuously true in code. I don't really like the idea of turning a
perfectly good and properly documented mathematical test into an error
in order to protect against a possible "thought-bug".

RFC: Dealing with out of tree changes and the LLVM git monorepo
Thanks for writing this up. I think it's a really important point which
deserves discussion.
Ultimately, I think it is a question as to whether to prioritize the easy
switchover for existing out of tree forks, or to prioritize having the best
conversion we can make. I feel very strongly that the latter should be the
priority for the official repository conversion, and that, therefore, we

Unobtrusive scripting?
Currently, pages generated by Rails tend to be sprinkled with
JavaScript. This happens, because the various helper methods work only
locally and simply append to the output.
In order to hide the JavaScript away, rendering would probably have to
be changed. A way I can think of is that a page-specific script is
included in the head of the document and JavaScript code is not written
to the
