Error in La_library() : LAPACK routines cannot be loaded

[chrisdane]

Hi!

In r, I do

> install.packages("ropenblas")
> library(ropenblas)
> ropenblas::ropenblas()
...
Install OK!
make[1]: Leaving directory '/tmp/openblas'
ℹ Running command: `sudo ln -snf /opt/OpenBLAS/lib/libopenblas.so '/usr/lib/libblas.so.3.12.0'`
During startup - Warning message:
package ‘stats’ in options("defaultPackages") was not found 
────────────────────────────────────────────────────────────── Procedure Completed ──────────────────────────────────────────────────────────────
✔ OpenBLAS version 0.3.30 successfully linked.
ℹ IMPORTANT: Please restart your R session manually for the changes to take effect.
> q()

and in a new r session a warning appears on startup (was not there before the ropenblas-call) and an error on sessionInfo:

During startup - Warning message:
package ‘stats’ in options("defaultPackages") was not found 
> sessionInfo()
Error in La_library() : LAPACK routines cannot be loaded
In addition: Warning message:
In La_library() :
