Sounds reasonable, but I leave it to wiser heads than me to decide. My
only point is that whatever is done be accurately documented. At
present, that does not appear to be the case. ... and yes, "accurate"
documentation is not easy either.

Thanks, I had missed/forgotten the fact that there is also an
inconsistency between mean.default() and sd().
sd() calls var(), which evaluates if(na.rm) [i.e., it will try to
coerce `na.rm` to logical rather than testing isTRUE]
IM(H?)O, it would be best for both mean.default() and sd()
Ivo, et al.:

Defining, let alone enforcing, "consistent behavior" can be a
philosophical conundrum: what one person deems "consistent" behavior
for a function across different data structures and circumstances may
not be the same as another's. While
less error prone.
I don't blame you for being teed off at why things where not working when T
was redefined.

This example is a little more subtle than that; the OP knows about
name masking, but was expecting T to be coerced to logical, which
would ordinarily be a reasonable expectation (IMO) ...

isn't this still a little R buglet? I have overwritten T (even if my
schuld [franconian], it is not that uncommon an error, because T is also a
common abbreviation for the end of a time series; namespace pollution in R
can be quite annoying, even though I understand that it is convenient in

I've not checked the code, but I think that result would happen if mean
uses something like
if (na.rm == TRUE) {
# do something to remove the NA's
}
And as uses something like
If (na.rm != FALSE) {
# do something to remove the NA's
}
Or perhaps ever na.rm == T

Is the following a strange behavior for `mean` vs. `sd` ?
