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 


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):


(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:


to your PROJ_LIB location.
