Hi, Paul:
"if(!fda::CRAN())" runs code except with "R CMD check ?as-cran".
I use it so CRAN checks skip examples that (a) need the Internet or (b)
take too long for CRAN.
Spencer fda::CRAN() gives TRUE on my home machine, I think because I use several variables like _R_CHECK_HAVE_MYSQL_=TRUE to control whether some tests get run. (Not all CRAN test servers have all resources.) But, more importantly, wouldn't this strategy prevent CRAN from automatically running more extensive testing of the examples if they decided to do that sometimes? Paul
Hope this helps.

Is there a good strategy for testing examples which should not be run by default? For instance, I have examples which get data from the Internet. If I wrap them in try() then they can be skipped if the Internet is not available, but may not be tested in cases when I would like to know about the failure. (Not to mention that the example syntax is ugly.) If I mark them \dontrun or \donttest then they are not tested. I could mark them \dontrun and then use example() but for this, in addition to run.dontrun=TRUE, I would need to specify all topics for a package, and I don't see how to do this, missing topic does not work. Wishlist: what I would really like is R CMD check --run-dontrun pkg Suggestions? Thanks, Paul
