Hi Matt,

I am still having the same error message  with version 1.2-14.

The problem persists even after using a  small subset of the data and substituting some variables.

Thank you for your assistance.

Hi Ndiaye,

Do you still have this problem on the latest version of Amelia? You should see the version number when you load the Amelia package. The most current version is 1.2-14. 

Thanks!

After the following R commands:

a.out<-amelia(bd2,m=5 ,idvars =c("bd_id",”cty”),noms=c("race4","outc")) ,

I received this error message:

“Error in if (sum(non.vary == 0)) { :

  argument is not interpretable as logical”

What that means?

I used the current versions of R and Amelia on Windows

The data contains more than 100,000 records, with 6 variables. They are all factors except bwt3, a continuous variable.

See below the first rows of the data frame bd2:

> head(bd2)

bd_id	race4	outc	cty	bwt3
1989-35129	1	1	0	2665
1989-43790	2	1	0	3685
1989-44528	1	1	0	3402
1989-48485	1	1	0	3175
1989-49402	1	1	0	3742
1989-55241	4	1	0	3941

Thanks you for any help.
