I get a warning about "1 warning message" using R CMD check on the
survival library. It comes from the code snippet:
if (library(cmprsk, logical.return=TRUE)) {
# further test of competing risks from survfit
.
.
}
This is a very useful additional test when I'm checking any changes to
the affected code, so I like having this in my test suite even though it
doesn't run automatically.
This argues for a change in library -- when the user sets logical.return
=T they don't need a warning message too.
It was the considered opinion that in general they do. You can always
use suppressWarnings() in your code if you don't, or you can pre-check
that the package is available via lower-level functions such as
.packages and .find.package.
I submit this to the R core and their collective wisdom.
I admit that mine is an unusual case, and for now I'll turn if off with
options(warn=-1)
