[Rcpp-devel] xts inputs and outputs for Rcpp translation

[Hideyoshi Maeda]

I was aware that an xts object is just a NumericMatrix with a few attributes and index attached, but was wondering if anybody could please give me a walkthrough example to show me how its done with some thing that has more than one column and also how one goes about subsetting columns of the xts object/matrix etc.

any help as always would be greatly appreciated.

Thanks

HLM
