That should be good enough. | FWIW, "MatrixExtra" installs without problems for me on "ancient" I am fairly certain that the (accidental ?) mishap of mixing current R, i.e. his 4.1.2, with a 3.5.1 library is the issue. It has been so long since I converted from pre-4.0.* that I forgot what the error message looks like but the arcanae one in David's post may qualify. | > R version 4.1.2 (2021-11-01) | > Platform: x86_64-pc-linux-gnu (64-bit) | > Running under: Ubuntu 18.04.6 LTS | > | > Matrix products: default | > BLAS: /usr/lib/x86_64-linux-gnu/blas/libblas.so.3.7.1 | > LAPACK: /usr/lib/x86_64-linux-gnu/lapack/liblapack.so.3.7.1 | | I see openblas in your sessionInfo().
