88 hits for "zero-inflated" on R-Search:
http://search.r-project.org/cgi-bin/namazu.cgi?query=%22zero-inflated%22&max=100&result=normal&sort=score&idxname=functions&idxname=Rhelp08&idxname=views

One hit for "zero-modified" ....  which _was_ in the actuar package:
http://finzi.psych.upenn.edu/R/library/actuar/html/aggregateDist.html

11 hits for "hurdle model"
http://search.r-project.org/cgi-bin/namazu.cgi?query=%22hurdle+model%22&max=100&result=normal&sort=score&idxname=functions&idxname=Rhelp08&idxname=views

And then there would also be zero-altered negative binomial and  
Poisson models:

Hope this helps;
