[amelia] Broken Functionality in Amelia package for R (Version 1.2-9, built: 2009-07-02)

Hello, I believe the latest update to the Amelia package for R has inadvertently broken some essential functionality. Using a sample dataset available here<http://www.princeton.edu/%7Ewbullock/sampleData.RData>ta>, I'm using the following code: library(Amelia) load("sampleData.RData") test <- amelia(sampleData, idvars=c("st"), noms=c("female","imports"), ords=c("age", "edu", "inc")) On one computer using Version 1.2-2, built: 2009-04-27 available via the CRAN archives, everything goes well. On a second computer using Version 1.2-9, built: 2009-07-02 I get: Error in sum(sapply(x[, fact], is.factor)) : invalid 'type' (list) of argument It appears as though amelia is having trouble taking in a vector of column names, but I must admit I haven't done extensive testing of the problem. Any help would be much appreciated. Sincerely, --Will Bullock Department of Politics Princeton University
