"In theory, theory and practice are the same. In practice, they are not."

The main test script long had exactly such a setting; I wrote what I wrote
because it is _still the wrong way around_ and as I happen to have added
to
unit tests this weekend _having suffered through precisely this setting_.

But we are on different wavelengths here and I evidently do not get my
point
across to you.  And as you are the one who could make a change where it
matters, I have no choice but to rest my case in frustration.

If you want to give up, then give up, but then don't complain about the
current behaviour.  If you want to fix it, then continue the discussion.

You're right that we're on different wavelengths.  If you want some tests to
run at home but not on CRAN, then somewhere there has to be a conditional.
I'm suggesting that the conditional should be "if there's a tight time
limit, skip this".

I don't remember if this was your suggestion, but someone has suggested "if
we're running with the --as-cran option, skip this" and others have
suggested "if we're running on CRAN, skip this".   I don't see why you find
my suggestion so objectionable.  If you want, I'll repeat why I find the
other two suggestions objectionable.

I agree with Duncan that having an option long/short makes more sense
than with/without cran, as long as cran sets that option to be short.

I would also prefer a command line switch to R CMD check to an
environment variable, but I'll be very happy with a standardized
environment variable.
