[R] R C API resize matrice

[Bert Gunter]

Please do not re-post -- you have asked this before here. As this list is
about R programming help, it is perhaps not surprising that you did not
receive a reply.

You might try R-devel instead where " Questions likely to prompt discussion
unintelligible to non-programmers or topics that are too technical for
R-help’s audience should go to R-devel..."

Cheers,
Bert
