Hello,
Which version of Rcpp is this ? I think this has been fixed in 0.7.11

Hi,
If you want to compile the code that is here
http://dirk.eddelbuettel.com/code/rcpp.armadillo.html directly from R
CMD SHLIB, you can do this:
rom...@naxos /tmp $ export PKG_CXXFLAGS=`Rscript -e
"RcppArmadillo:::CxxFlags()"`
rom...@naxos /tmp $ export PKG_LIBS=`Rscript -e "RcppArmadillo:::

Hi,
I'm a bit puzzled. I uses exactly the same code in RcppExamples
package to try adding RcppFrame object to RcppResultSet. When running
it gives me segmentation fault problem. I'm using gcc 4.1.2 on redhat
64bit. I'm not sure if this is the cause of the problem. Any advice
would be greatly appre
Most Lapack routines for solving linear systems from factorizations
allow the right hand side to be a matrix, thereby providing for
solving multiple systems in one call. I would like to preserve this
capability while also allowing for the most common case where the rhs
is a vector. Also, I would
