Hi all,
I've been trying to include a nice example in the Rd file for a function
and cannot work out how to get it through R check. If I use:
if(require(maps,quietly=TRUE)) {
...
Warning message:
'Sys.putenv' is deprecated.
Use 'Sys.setenv' instead.
See help("Deprecated")
require() doesn't use Sys.putenv, so I'd guess some package that you're
loading does. However, the current version of maps doesn't, so I think
you must be loading something that's obsolete.
sessionInfo() would have helped a lot.

The warning message causes R check to get the tremors and assume there
is something wrong with the example. This also means that I can't put a
little message telling the user that they needed "maps" to run the
example, as the warning message leads to the "else" being detached from
the "if" (and another tremor and error message).
I can't really use the following, even though it doesn't cause the
warning (but would be messy if the user didn't have the package).
if(library(maps)) {
...
If I try:
if(library(maps,logical.return=TRUE)) {
...
I get the same warning as with "require". Does this qualify as a bug in
require/library or should I just not bother to test the result of
"library" and let the user suffer?
