  • You seem to be missing required system libraries: Lapack and BLAS. (Not really an R problem.) Possible duplicate of https://stackoverflow.com/questions/36676449/lapack-blas-openblas-proper-installation-from-source-replace-system-libraries – IRTFM Apr 15 '18 at 18:35

  • `sudo apt-get install libblas-dev liblapack-dev` should be enougth – JRR Apr 15 '18 at 19:15

    This does make me wonder whether you installed the proper R packages. How long have you been using R? I would have imagined the liblapack should be part of the r-dev package. – IRTFM Apr 15 '18 at 19:32
