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: http://finzi.psych.upenn.edu/library/Hmisc/html/transace.html I'm not sure that this does the same thing as ace.
