Dear list,
When calling R from C, what appears like a spurious error can be
triggered during the execution of chisq.test(x, y).
This is happening when the following conditions are met:
- x and y are anonymous C-level R vectors (they do not have a symbol),
but
This is easy to reproduce in R:
chisq.test(c(1000, 1001, 1002, 1003, 1004, 1005, 1006, 1007, 1008, 1009, 1010,

The simple answer is: don't do that.
It is unclear what is a reasonable label to give in such a
Hi Ravi,
I just briefly looked at the code (and haven't run it). But it seems
like there is still the underlying problem that '...' argument is sent
to both optim and f. The documentation says that ... arguments are sent
to optim, so at least based on this the ... should only appear in optim.

About PR#14067, now I understand why (Date + difftime) does not use '+.Date'.
But, before I understand, it was surprising. The surprise is also reflected in
the post Problem with +(POSIXt, difftime)
Thanks to you and Peter for the quick answer.
I should definitely have tried I R. It just seemed to me so unlikely
that no one ever reported that anonymous vectors would fail with
chisq.test().
Having a label that would be x or y is along the lines of something I
was thinking of, and this

Hi Kevin,
What a surprising comment from a reviewer for BMC Bioinformatics.
I just did a PubMed search for limma and aroma.affymetrix,
just two methods for which I use R software regularly.
limma yields 28 hits, several of which are published
in BMC Bioinformatics. Bengtsson's aroma.affymetrix

Arrays of POSIXlt dates always return a length of 9. This
is correct (they're really lists of vectors of seconds,
hours, and so forth), but other methods disguise them as
flat vectors, giving superficially surprising behaviour:

dates -
Check the documentation and the archives. Not a bug. b

I've checked the archives, and this problem crops up every
few months going back for years.
What I was not able to find was an explanation of why a
function such as
length.POSIXlt - function(x) { length(x$sec) }
is a Bad Idea, or what it would break. listserv threads

Time difference of 1 mins

Steve,
I'm no expert on this, but my understanding is that the choice was to
stick to the definition.
The help file for length() [1] says:
For vectors (including lists) and factors the length is the number of
elements.
The help file for POSIXlt [2] (for example) says:
Class ‘POSIXlt’

This is not a bug, and has nothing to do with times. For example:

Formatting is not the same as rounding. Perhaps you are assuming R
formats numbers according to the concept of significant digits, but
it doesn't. See the help page for the format function to get started
