[amelia] integer-related bug in amcheck

Hi all, I get a strange bug when using the "disperse" function with some ordinal variables. The output of Amelia correctly gives these ordinal variables integer values. However, they are stored in R as numeric types. When I call "disperse", it calls the Amelia internal function "amcheck". A few of the ordinal variables then fail the test if (any(unique(na.omit(x[, i]))%%1 != 0)) and the disperse function fails. Here's a simple test case that fails for me: tmp <- data.frame(a=1:10000, b=round(rnorm(100000,0,3))) tmp$b[1:2000*5] <- NA a.out.try <- amelia(tmp, ords="b") disperse(a.out.try) David Hugh-Jones Post-doctoral Researcher Max Planck Institute of Economics, Jena http://davidhughjones.googlepages.com - Amelia mailing list served by Harvard-MIT Data Center [Un]Subscribe/View Archive: http://lists.gking.harvard.edu/?info=amelia More info about Amelia: http://gking.harvard.edu/amelia
