- CHANGES IN R 3.6.2:
NEW FEATURES:
* runmed(x, *) gains a new option na.action determining _how_ to
handle NaN or NA in x.
* dotchart() gains new options ann, xaxt, frame.plot and log.
INSTALLATION on a UNIX-ALIKE:
* Detection of the C stack direction has been moved from run-time
to configure: this is safer with LTO builds and allows the
detection to be overridden - see file config.site.
* Source-code changes enable installation on platforms using gcc
-fno-common (the expected default for gcc 10.x).
C-LEVEL FACILITIES:
* installTrChar (which is nowadays is wrapped by installChar) is
defined in Rinternals.h. (Neither are part of the API.)
PACKAGE INSTALLATION:
* Header Rconfig.h contains the value of FC_LEN_T deduced at
installation which is used by the prototypes in headers
R_ext/BLAS.h and R_ext/Lapack.h but to avoid extensive breakage
this is only exposed when USE_FC_LEN_T is defined.
If a package's C/C++ calls to BLAS/LAPACK allow for the 'hidden'
arguments used by most Fortran compilers to pass the lengths of
Fortran character arguments, define USE_FC_LEN_T and include
Rconfig.h (possibly _via_ R.h) before including R_ext/BLAS.h or
R_ext/Lapack.h.
* A package with Fortran source code and perhaps C (but not C++)
sources can request for its shared object/DLL to be linked by the
Fortran compiler by including a line USE_FC_TO_LINK= in
src/Makevars[.win] and using $(SHLIB_OPENMP_FFLAGS) as part of
PKG_LIBS.
The known reason for doing so is a package which uses Fortran
