What does   sessionInfo()   show?  For me on this computer it is

  R> sessionInfo()
  R version 3.5.1 (2018-07-02)
  Platform: x86_64-pc-linux-gnu (64-bit)
  Running under: Ubuntu 18.04.1 LTS

  Matrix products: default
  BLAS: /usr/lib/x86_64-linux-gnu/openblas/libblas.so.3
  LAPACK: /usr/lib/x86_64-linux-gnu/libopenblasp-r0.2.20.so
  [...]


If Mint follows the setup I use for the Debian package, then you _never have
libRblas.so_ because we use the _external_ BLAS.  This allows you to switch
to Atlas (tuned BLAS), OpenBLAS (multithreaded), Intel MKL (multithreaded and
possibly a little faster than OpenBLAS but much bigger), ...
