Hi Roger, Thanks for the updated rgdal and for all the information. After upgrading rgdal earlier today I got the warning message for nearly all raster/sp/rgdal operations in R. On a Mac running Yosemite, this is the path I had to copy the proj_def.dat file to (or where I had to create a new file based on the link you've provided): /opt/local/share/proj/ This path assumes that PROJ was installed from MacPorts on its default directory.
Thanks very much for reporting back, and for indicating a resolution for others in the same situation. I believe that those running the CRAN OSX rgdal binary are protected because it ships with the metadata files. A release candidate for PROJ 4.9.2 was issues yesterday evening, and will provide a solution to the problem, but because other issues also need addressing, it may be a little while before it is out, and propagates to MacPorts, etc. Roger

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. Roger
