R

Hi,

I thought I'd respond to this old thread now that the openblas eigen 
error seems to be fixed. I'm interested in using openblas so that the 
(as yet not in master) WGCNA package works faster, among other things:

Shall I push the attached patch to core-updates? I tested it on x86_64. 
Or, would you mind testing it on arm please Andreas?

Thanks,

The patch looks fine to me and I’m generally in favour of adding
OpenBLAS to R.  

I should note that the R admin manual[1] says that the correct configure
flag for OpenBLAS is

    --with-blas="-lopenblas"

I’m not sure if this makes a difference.

OpenBLAS works fine for me - hit the same issue with Python before.

Thanks. I changed it to that minus the double quotes, and updated to 
3.3.1, then pushed to core-updated. We'll see how things go.
