[R] Problem with gridExtra

[Richard M. Heiberger]

gridExtra was changed.  This is the email from Baptiste to CRAN package
developers that describes the changes and
points to the vignettes that will describe the changes.  The changes
described here are now in the current release of gridExtra.

Dear package maintainers,

I'm working on a long-overdue update of gridExtra for CRAN, and I believe
your package depends on it. Please have a look at the dev version on
github, and let me know if it breaks something in your package.

https://github.com/baptiste/gridextra

I've removed practically everything; only two main functions are left:
grid.arrange(),
and grid.table(). I believe they were by-and-large the only ones actually
used, and the rest was mostly experimental code that shouldn't stay on
CRAN.
I've rewritten these two functions using gtable, which I found more
practical and extensible. However, this means that the new functions are
entirely different from their predecessor, internally, and may break a lot
of code. I have included two vignettes for an overview of these updated
functions, also reproduced in the wiki:

Regards,

baptiste
