[amelia] Errors in "overimpute" and "compare.density"

Dear all, I am running into some problems with the newest version of Amelia II and I cannot figure out exactly why, and I hope you can shed some lights on these issues that I am running into. I have successfully imputed 10 dataset by using Amelia II in R. The imputed datasets look good, so is the overdispersed graph. However, when I try to run "overimpute" and "compare.density" to conduct more diagnostics for some specific variables, I am getting the following error messages: Error in density.default(vars[!is.na(vars)], na.rm = TRUE) : argument 'x' must be numeric Error in segments(xplot[ci.order], lowers[ci.order], xplot[ci.order], : invalid first argument I double-check and make sure variable 13 is indeed numeric, but they have non-English labels. I have used an older version of Amelia II and imputed a similar dataset a couple years before, and I have no problem using these diagnostics commands in R. Now that I have the most up-to-date version of Amelia II on a new computer, I am running into these problems. Any suggestions will be greatly appreciated. Thanks a lot in advance.
