Now that Rcpp got updated to 0.8.6
we have an updated RcppArmadillo
release containing mostly updates to Conrad's
version 0.9.70 as well
as some more templated sugar magic.
makes it easy to write highly efficient and highly readable C++ code for linear algebra (based
on Armadillo) in R extensions (using Rcpp
for the interface).
The short NEWS file extract follows:
o Upgraded to Armadillo 0.9.70 "Subtropical Winter Safari"
o arma::Mat, arma::Row and arma::Col get constructor that take vector
or matrix sugar expressions. See the unit test "test.armadillo.sugar.ctor"
and "test.armadillo.sugar.matrix.ctor" for examples.
More information is on the
Questions, comments etc should go to the
rcpp-devel mailing list
off the R-Forge page.
