Thanks for responding - every user data point helps!

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.
