[R-sig-Geo] CRAN releases of sp, rgdal and rgeos

[MacQueen, Don]

Success!

This morning I upgraded a Mac to OS 10.13.5 (the so-called High Sierra version), then

 - Installed R 3.5.0 from CRAN (installed ever 3.3.x)
 - Installed sp 1.3-1, rgdal 1.3-2, rgeos 0.3-28, also sf 0.6-3, from the CRAN binaries that are now available
 - Ran my personal test suite, which exercises the kinds of tasks I perform with those packages

All tests succeeded.

I forgot to control the order of installation, so I don't know if I installed sp first, as advised. But I expect that with the binary versions it doesn't matter.

(I don't think it matters for the above, but I also installed the clang and gfortran version provided on CRAN's Mac "tools" page, and successfully compiled some source packages that require fortran, and others that require C).

Thank again for all your work
-Don

    There are new releases of sp, rgdal and rgeos on CRAN. Please install sp 
    first, then the other two, which link to the installed sp. They all 
    address so-called rchk issues, which have not so far been a problem, but 
    might have become more fragile as R's internal memory management is made 
    even more efficient. This involves compiled code using memory allocated by 
    R to be freed by R's garbage collector, which has to know if an object is 
    still being used. Tomas Kalibera, the author of rchk, helped resolve and 
    explain the issues encountered - what was good coding practice fifteen 
    years ago isn't always still good practice.
    
    In addition, the earliest versions of GDAL and PROJ with which rgdal will 
    work have been updated, and set to PROJ 4.8.0 and GDAL 1.11.4. The current 
    released versions of PROJ and GDAL are to be prefered, as bugs have been 
    fixed and new features and drivers introduced. A check has been put 
    in place to trap attempts to install rgdal without a C++11-capable 
    compiler when the GDAL version is >=2.3.0 - which requires C++11. rgeos is 
    ready for the forthcoming version of GEOS.
    
    The CRAN team has also been very supportive of our efforts to bring 
    compiled code in these packages into rchk compliance.
    
    Please get in touch if you see any loose ends in these releases.
