Don't know that myself. Asking admin now.

Dear list,
I'm trying to install RcppArmadillo on my school's cluster (R version
2012-05-31 r59485). Was able to install Rcpp fine using
install.packages. However, I get the following error for Rcpp:
> install.packages("RcppArmadillo", lib="~/Rlib", dep=TRUE)
trying URL 'http://cran.stat.ucla.e
Dear Rcpp List,
My goal is to write a generic C++ optimizing function (call it "optim"
in this email) based on the Newton-Raphson algorithm. I will be
passing into the optimizing function 4 arguments:
1. (pointer to) a function, "f1", to be optimized,
2. an initial value/vector,
3. the remaini

Thanks Dirk. I've been using the package skeleton method, and added
PKG_CXXFLAGS = $(shell $(R_HOME)/bin/Rscript -e "Rcpp:::CxxFlags()" )
$(shell Rscript -e "cat( '-I',
system.file('include', package = 'RcppArmadillo'), sep = '' )" )
into the Makevars file per Romain's suggestion.
RcppArmadillo:
Two questions:
1. The main difference when using RcppArmadillo and Rcpp is the
header declaration and the return type for the function right?
extern "C" SEXP fastLm(SEXP ys, SEXP Xs) {}
RcppArmadillo takes this extern stuff whereas Rcpp takes RcppExport?
RcppExport SEXP newRcppVectorExample(SEXP
es and the package built without an error.
Thanks.
Vinh

Thanks for the prompt response. My o
Dear Rcpp list,
It's time for me to finally try out Rcpp since I have to do some
computing for my research. Some questions (please be kind as I'm only
a beginner C programmer using .C() and not smart enough to understand .
Call()):
1. I plan to use objects like
Rcpp::NumericMatrix orig(matrix);
