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) Terry T. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
