Hi,
Thank Dirk first for replying to my previous questions so fast.
Another question:
Suppose I have a function in CPP as
void cppfun(Rcpp::List lst) {
..
}
Then I would like to call this cppfun in R code as say
cppfun(list(a=a, b=b, c=c, ...)), in which
a, b, c could be of different t

I have followed the Rcpp developer's recommendation that a package
greatly simplifies using RCPP_MODULE wrappering. Unfortunately, I'm
having difficulty building and checking even a simple package

Dear Douglas,
many thanks for your quick reply, that's exactly what I was looking for.
