I ran Amelia in R-Studio and I got the error below.

I believe the problem variables are labeled as ID vars and I'd like to leave them as ID vars. If anyone has a solution, please let me know.

Many Thanks,

Error in amelia.default(x, m = 5, idvars = c("caseid", "strata", "prov",  : 

  (list) object cannot be coerced to type 'double'

In addition: There were 20 warnings (use warnings() to see them)
