Guys,

I can see no built-in support for zoo objects in Rcpp (I seem to recall there was support on the old version), is that right?

If it is has anyone written an extension supporting zoo and is willing to share?

Cheers!

//Giuseppe

Maybe you refer to cxxPack:
http://cran.r-project.org/web/packages/cxxPack/index.html

It does not appear to work these days, according to CRAN checks:

I have always split this into a vector of times (trivially using as.numeric()
first on the POSIXct data to use double precision fractional times -- before
I had added a Datetime class) and matrix of data.  You get microsecond
precision (on Linux, Windows only does milliseconds) that way in a format
that is native to C/C++ as well.

That was always good enough for me. Working patches for zoo (or better still,
xts) would be considered.

As Romain said, cxxPack once went that way, but then cxxPack also ceased to
function or be supported over six months ago.  

But this is not the list to discuss cxxPack.
