I agree.... but the CRAN maintainers have to agree too.

yes, my packages do their own thing too, now, e.g., Matrix
(not yet released):
doExtras <- interactive() || nzchar(Sys.getenv("R_MATRIX_CHECK_EXTRA")) ||
identical("true", unname(Sys.getenv("R_PKG_CHECKING_doExtras")))
and then I use if(doExtras) { .... }
but I agree with Henrik that it would make sense to have more
than just two levels for the amount of testing, not just for CRAN.
An additional, slightly more interesting feature request that
you may also want in these cases, is the following:
Assume, that we have a function testingLevel()
and the following code should only be run, if the testing level
is 2 or higher
if(testingLevel() > 2) {
.......1
.......2
........
........
.......n
}
Now what we all really wanted was that the ........ code
ran just as in toplevel.
While I think that's almost impossible,
as the .....1 to .....n must first be parsed all, and then
evaluated (which is already different from top level),
I would at least want that the auto-printing worked like in
toplevel, so I don't have to write a print(.) around every
......i that would autoprint if in toplevel, and of course does
*not* autoprint inside if(.) { .. }.
