I tried following these instructions with ATLAS 3.8.4-8 on Ubuntu 12.04,
got the .deb files, but I get conflicts with libblas3gf (see below), any
ideas?
Thanks,
Gad

make check fails with default libblas
Dear All,
Summary:
========
To test some packages, I want to build R-3.1.0 (current R devel). However,
when I use the default libblas, make check fails with
running code in 'reg-BLAS.R' ...make[3]: *** [reg-BLAS.Rout] Error 1
It does not fail, however, if I use libatlas3 or libopenblas.
The same thing happens with the current R patched.
I've google around and cannot find anything, and I find it very surprising
that make check fails here.
Details:
========
- I have checked this with R-devel from 19 December and 26 December, as
well as with the current R...

stock ubuntu raring binary R 3.0.1 and accelerated blas libraries?
...ring but on
cinnamon mint olivia 15.
I read dirk's gcbd paper from a couple of years ago. it suggests that
stock blas is pretty bad compared to the four main alternatives. of
course, dirk also maintains the binaries for debian/ubuntu R, so he
probably knows the answer off hand.
I installed libatlas3-base (3.8.4-9ubuntu1) from the software
repositories. ldd tells me that this is not enough ( ldd
/usr/lib/R/bin/exec/R | grep -i atlas). libatlas use is not determined at
compile time. I also redownloaded the 'r-base' binary to check whether it
is determined at download time. this did...

optimized linear algebra library on Lenny
...'apt-get install atlas3-base' for basic tuned Atlas, or
'apt-get install atlas3-sse2' assuming that sse2 is the closest fit to the
cpu in question.
</quote>
However, while atlas3-base is available in Lenny/Testing, none of the
architecture-dependent extensions are. I did find libatlas3gf-*, is this
the same thing?
The information I found in the R Admin manual seems to apply only to
building R yourself, so I'm not sure what to do with the precompiled
version from the repository. Is it as simple as:
apt-get install libatlas3gf-sse2
And is there anything else that needs doing...

Function nlme::lme in Ubuntu (but not Win or OS X): "Non-positive definite approximate variance-covariance"
Dear all,
I am estimating a mixed-model in Ubuntu Raring (13.04ΒΈ amd64), with the
code:
fm0 <- lme(rt ~ run + group * stim * cond,
random=list(
subj=pdSymm(~ 1 + run),
subj=pdSymm(~ 0 + stim)),
data=mydat1)
When I check the approximate variance-covariance matrix, I get:
