Yes -- there isn't much yet in RcppArmadillo but this is expected to grow. And CRAN now has rARPACK so we get cheaply to the object code too. One last comment I should have made earlier: "dense" data from R comes over cheaply as a SEXP; "sparse" will always require a copy. Keep that in mind, and on the margin don't believe anything any of us say but keep profiling and measuring :) Dirk -- Dirk Eddelbuettel | [email protected] | http://dirk.eddelbuettel.com _______________________________________________ Rcpp-devel mailing list [email protected] https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/rcpp-devel
