[R-pkg-devel] Warnings from gdal

[Trent McDonald]

Hope this helps.  I had a similar issue with my package.  Prior to the
recent change, GDAL did not throw a warning for empty (NA) CRS
strings. After change, it does.  projectRaster is throwing the warning
because it thinks input and output crs are the same (perhaps CRS is
missing?).  The purpose of projectRaster is to change crs's, so
identical crs's make little sense. I suggest making sure the input CRS
is valid (not NA) and that output CRS is different than the input.

'rgdal' now throws a warning if 'crs' is used,  and unless I am misreading the problems (see https://cran.r-project.org/web/checks/check_results_rerddapXtracto.html) that is what is causing the problems.  I am not certain that I can suppress warnings because it is from a package that calls a package (in this case raster) that calls rgdal.
