Max and Ben got the right answer. It is a bug with mclapply dropping
warnings. I confirmed by a quick change to the code to just use lapply,
and the warnings appeared as expected.
I've submitted the bug at

Thanks for the help!

Digging into the code (specifically by setting
options(warn=2,error=recover), I see that the warning is happening
during this call:
tmp.results <- parallel::mclapply(X = conc.dose, FUN =
pk.nca.intervals,
intervals = data$intervals, options = data$options)
Since mclapply "relies on fo
Hi Bill,
This is just a hypothesis, but it could have something to do with the
fact that you're using parallel::mclapply inside your function pk.nca?
This would certainly explain why you have different behaviours on
Windows and Unix systems. It would also explain why you get a different
behav
Hi François,
I thought that was the issue, too, but I confirmed it wasn't that by
adding a print statement right above the warning in my code. The print
statement displays the message even when the warning (one line below
with no conditionals between) doesn't show anything.
Also, why would i
Hi Bill,
The problem is not with the warning() function but with your if()
test that triggers the warning. It probably has something to do with
slight differences in rounding. I suggest you use debug() or browser()
on each platform to see why your condition is TRUE or FALSE.

Hi,

warning behavior on different operating systems that I can't figure out.
When I run the following code on Windows 10 (with R 3.3.0), I get the
following warning:
