In other words, I tend to use standard blas or openblas or atlas (but
seemingly less often). Both are 17.04, but that doesn't matter as they both
have been updated regularly over the years.
You must have gotten out of whack between what compiled R, and what runs it.
Did you by chance compile R 3.4.3 locally?
Yes, first I installed R-3.4.3 from source and it started OK, but when I
tried
> library(eha)
I got the error above.
So I installed by apt, and then I got the above.
This is what I always have done, installing both from source and the
ubuntu versions via 'apt upgrade', and it has always worked without
problems. What has changed now? And how can I get out of this?
