Hi everyone,
I'd appreciate some help on this: I need to use mixtools on R in sage
for the ER stuff they have. It turns out you need R 3.2.4 or better.
I thought of (a) upgrading the sage internal R or (b) using the system
wide one that I have on sagemath 7.2, passing data back and forth from sage
any thoughts on this please ? how could some thing like this be achieved ?
Using system R through the pexpect should work just fine. Issues will
crop up when you use the rpy interface since this is tied up with
libR.so from the local install.
It may pick up your system wide R if you scrub the existing sage install
of R completely (not just local/bin/R but also the local/lib/R folder).
Because libR.so is not in usr/lib{64} but in /usr/lib{64}/R/lib there
may be some LD_LIBRARY_PATH gymnastics involved.
