[R] does any package have the functionality of ace() from old acepack?

[Jonathan Baron]

Acepack is still in the archive section of CRAN:

http://cran.r-project.org/src/contrib/Archive/acepack/acepack_1.3-2.2.tar.gz

It seems to work despite the warning, but I guess you'd better test
it.

It is very simple: a few very old fortran scripts and an R wrapper by
Thomas Lumley.  I'm going to look into what needs to be done to bring
it up to date, but no promises.

A similar function is transace from the Hmisc package:

I'm not sure that this does the same thing as ace.
