[Rcpp-devel] trans() changed in latest RcppArmadillo

Hello, After upgrading to the 0.2.21 release of RcppArmadillo, my
previously working code (across many functions) ceased working (on a
Windows XP installation).  I re-installed the previous version (0.2.20)
from CRAN (via a server location not yet updated to 0.2.21); didn't fix
it.   The timing may be a coincidence, though reading the post on
trans() encourages me to make this post.  While I use 'trans' across my
functions, it is not applied on complex-valued matrices; only
real-valued.  So the prior post wouldn't explain my issue.

 

Thanks, Terrance Savitsky

As should be clear from the NEWS file I posted, 0.2.20 and 0.2.21 are both
using pre-releases of Armadillo 2.0.0 --- so you get the 'new' trans() and
other behaviour in both cases. Conrad's 1.99.2 in 0.2.20 brought a lot of
changes.

Hence you want to download 0.2.19 which uses Armadillo 1.2.0.  

Actual bug reports with replicable code would help us address any underlying
issues.
