A new version of rgdal has been accepted on CRAN. Users of CRAN binary
packages for Windows and OSX should not see any changes.
Other users of rgdal built against unpatched PROJ 4.9.1 will now see
(possibly many):
"NOTE: rgdal::checkCRSArgs: no proj_defs.dat in PROJ.4 shared files"
messages (also when rgdal is loaded silently by sp). This relates to the
release of PROJ 4.9.1 (an external dependency of rgdal), which by mistake
missed the proj_def.dat file of defaults, see this thread for a
discussion:
https://stat.ethz.ch/pipermail/r-sig-geo/2015-May/022849.html
The original fix to rgdal turned out (recently) not to be sufficient, so
please be aware that the use of +init= and +datum= on affected systems may
have erroneously injected the wrong +ellps= value. This release of rgdal
addresses these specific problems, but only a fresh release of PROJ will
resolve it.
Debian users may find it useful that a 4.9.1-3 version of proj-data now
has the errant file (on sid):
https://packages.debian.org/sid/all/proj-data/filelist
(thanks to Sebastiaan Couwenberg reacting very rapidly to my reminder
posted yesterday on the proj list).
If you update rgdal with an unpatched PROJ, you should see these messages
if you do anything with CRS objects. This will go away when a new PROJ
release appears, or until you add the missing file:
https://github.com/OSGeo/proj.4/blob/master/nad/proj_def.dat
to your PROJ_LIB location.
