The tests all pass on rhub Debian, CRAN windows, local OSX, and Travis Ubuntu. The tests that are failing on CRAN Debian are ones where I check that changes got made to an existing file that is modified in place by my package code.

According to the current master branch, the test that fails is not
using tempfile(), but "nc_file<-'data/test_output.nc'". Just change
that line with a call to tempfile and the test should pass.
