[R] Amelia error

[Gaurav Sood]

Sarah -

I have all the vars.. they all look sensible. I have been able to
trace the problem to NAs in the nominal variable, which is a bit
strange. The error that the program spits out is a class logical
equating error in presence of NAs etc. and hence was my hunch that it
was a bug.
