La_library {base}R Documentation

LAPACK Library


Report the name of the shared object file with LAPACK implementation in use.




A character vector of length one ("" when the name is not known). The value can be used as an indication of which LAPACK implementation is in use. Typically, the R version of LAPACK will appear as (libRlapack.dylib), depending on how R was built. Note that (libRlapack.dylib) may also be shown for an external LAPACK implementation that had been copied, hard-linked or renamed by the system administrator. Otherwise, the shared object file will be given and its path/name may indicate the vendor/version.

The detection does not work on Windows, nor for the Accelerate framework on macOS, nor in the rare (and unsupported) case of a static external library.

It is possible to build R against an enhanced BLAS which contains some but not all LAPACK routines, in which case this function reports the library containing routine ILAVER.
