I installed R in (what I believe is) the standard way by adding the following line to /etc/apt/sources.list
deb http://cran.us.r-project.org/bin/linux/ubuntu precise/ All was well, until I recently upgraded from 2.15.1 to 2.15.2 by running sudo apt-get update sudo apt-get upgrade Now, when I try to do simple things, I get an error. e.g. R> PP.test(rnorm(1000)) Error in chol2inv(Qr$qr[p1, p1, drop = FALSE]) : lapack routines cannot be loaded In addition: Warning message: In chol2inv(Qr$qr[p1, p1, drop = FALSE]) : unable to load shared object '/usr/lib/R/modules//lapack.so': /usr/lib/R/modules//lapack.so: undefined symbol: dpstrf_ I'm pretty sure I've never tried to build R from sources on this box. Does anyone have any advice for how I can remedy this error? Thanks, Garrett P.S.
