Subject: [R] predict.zeroinfl not found

Hi Just a quick problem that I hope is simple to resolve.  I'm doing some work with zero inflated poisson models using the pscl package. I can build models using zeroinfl and get outputs fom them with no problem, but when I try to use the predict.zeroinfl function, I get Error: could not find function "predict.zeroinfl".



I was using an older version of R, but still had the same problem when I installed 2.15.2.  I'm also using R studio 0.95.263 and am on a Windows 7 OS.



Many thanks,



Gavin.
