R help - Feb 2003 - arrays when calling C++ from R

Dear All,

I am writing some code in C++ that I call from R (using ".C"). I would
like to
have support for 2D and 3D arrays, including reading, assignment and 
operations over whole columns, rows, and slices, etc (with linear algebra a 
plus).  In the past I have used Blitz++ (oonumerics.org/blitz).  
However, I would eventually want to make that code a contributed package, and 
thus Blitz++ does not seem a good option (and, for the same reasons, probably 
neither is MTL). I am considering instead TNT (its "ancestor",
Lapack++, is
used in the Matrix package), or GSL. Does anybody have any suggestions as to 
the best way to go?

Thanks,
