Hi,
We now (in svn) have matrix-like indexing through operator() for all
vectors : (character, integer, numeric, raw, logical, generic and
expression).
Here is an example from the unit tests of NumericVector :
> funx <- cfunction(signature(x = "numeric" ), '
+ NumericVector m(x) ;
+ double tr

I think the Armadillo stuff is great. MTL4 is also great, but lacking

All the good libraries that I've seen allow you to construct objects
from a pointer to raw memory and dimensions which should be very easy
to write fo

yes, same issue for me in tslib. but (i,j) is not so bad esp for
matlab users. tslib users have it even harder since x() is used as
lag/lead. x[] is used a

Hello,
Motivated by Christophe's question on R-help (cc'ed), I'd like to add
facilities for matrix (and maybe arrays) indexing into the new Rcpp api.
The classic api already ships matrix indexing through RcppMatrix and
RcppMatrixView classes. I'm not a big fan of using round brackets for
index
