[amelia] Error of " resulting vector exceeds vector length limit in 'AnswerType'"

Dear Lister, I am using Amelia II (Version 1.6.4) with a 500 GB computer specification and my data consist of directed dyads and my imputation model has 94 variables and 493,853 observations. I use the following command: library(Amelia) library(foreign) mydata <- read.dta("data.dta") require(Amelia) set.seed(1234) a.out <- amelia(mydata, m=10, p2s = 2, tolerance = 0.005, empri = .1*nrow(mydata), ts="year", cs="dyadid" , polytime=2, intercs = TRUE) After 7 hours, I receive the following message: amelia starting beginning prep functions *Error in cbind(deparse.level, ...) :* * resulting vector exceeds vector length limit in 'AnswerType'* I've already searched the Amelia II archieves and R archives, I was not able to locate a solution. I would deeply appreciate any help!
