COMPILE
Compile Files for Use with R on Unix-alikes
Compile given source files so that they can subsequently be collected
into a shared object using R CMD SHLIB or an executable
program using R CMD LINK. Not available on Windows.

Usage
R CMD COMPILE [options] srcfilesArguments
- srcfiles
A list of the names of source files to be compiled. Currently, C, C++, Objective C, Objective C++ and Fortran are supported; the corresponding files should have the extensions
.c,.cc(or.cpp),.m,.mm(or.M),.fand.f90or.f95, respectively.- options
A list of compile-relevant settings, or for obtaining information about usage and version of the utility.
Details
R CMD SHLIB can both compile and link files into a
shared object: since it knows what run-time libraries are needed
when passed C++, Fortran and Objective C(++) sources, passing source
files to R CMD SHLIB is more reliable.
Objective C and Objective C++ support is optional and will work only if the corresponding compilers were available at R configure time: their main usage is on macOS.
Compilation arranges to include the paths to the R public C/C++ headers.
As this compiles code suitable for incorporation into a shared object, it generates PIC code: that might occasionally be undesirable for the main code of an executable program.
This is a make-based facility, so will not compile a source file
if a newer corresponding .o file is present.
Note
Some binary distributions of R have COMPILE in a separate
bundle, e.g.an R-devel RPM.
This is not available on Windows.
