Normally, I do symbolics in Maple, or Mathematica, but I'm trying to write a simple script for students to handle some *very* simple calculations (for other purposes) with matrix or vector elements, where the elements are coded symbolically. What I've tried with *partial" success is use of the tilde (~) operator. So, for example, consider a simple vector: test=matrix(c(~

Dear R users, The first version of the package ?horseshoe' is now available on CRAN. It contains various functions for implementing the horseshoe prior for sparse linear regression, and faster versions for the special case of the normal means problem. The functions output, among other things, the horseshoe estimator (posterior mean), credible intervals, and there is a function to perform

The management decided to switch over to Zimbra so we will no longer be using Dovecot...which served us exceedingly well. May Timo and the Dovecot community prosper. Thanks for all the help from all of you in the years since our switch from UW-IMAP. -- "Grant us, in our direst need, the smallest gifts: the nail of the horseshoe, the pin of the axle, the feather at the pivot point, the

I have a mix of CentOS 5, 6, and now 7 servers at work. There are enough of them now that it is starting to make sense for them to get updates from an internal source. I've seen RHN Satellite in years past. It looks like it may be a way to allow Windows admins here (familiar with WSUS) to update Linux boxes. A local repo might be easier to set up, but (as with Spacewalk) it seems like
