I am a newcomer to the Amelia mailing list and to Amelia.

I have a very large dataset (obs = 4696) with 232 variables (45 of which I am marking as idvars to remove them from the imputation model).

I am receiving an error message related to my use of the "empri" argument:

Error in amelia.default(x = SENSE.3, m = 5, p2s = 2, idvars = c("X", "srvagain",  : 
  formal argument "empri" matched by multiple actual arguments

because I am a novice user of R, I am not sure where this may be coming from. The code I used was copied from the AmeliaView() option, then modified, so perhaps there are syntax artifacts left over from copying that auto-produced code that I need to change?

Thanks for any indications.
