Conrad released 2.99.2 of Armadillo; this just became RcppArmadillo 0.2.38. As with 0.2.37 from last week, this is not on CRAN (and more about that at http://dirk.eddelbuettel.com/blog/) Once R-Forge updates (which is nightly, I think), you can do install.packages("RcppArmadillo", repos="http://R-Forge.R-project.org") and in the meantime it's on my site too. 0.2.38 2012-03-28 o Upgraded to Armadillo release 2.99.2 "Antarctic Chilli Ranch (Beta 2)" * added .i() * much faster handling of .col() and .row() * expressions X=A.i()*B and X=inv(A)*B are automatically converted to X=solve(A,B) Cheers, Dirk
