Hey Tim:

I'm writing the database as we speak which will take awhile but will then be
done. It is going faster than I thought it would. I figured out how to call
arc from the prompt and pass it an aml and variables from R:

        aml2pass <- paste('arc "&r make.an.image.aml', which.var, year,
                           formatC(month, width = 2, flag = 0), '"', sep = "

This means that I can write temporary files from arc, process them and clean
up without having a lot of loose ends. So, with that and rgdal, everything
is smooth. I'll leave GRASS for another day (I've been saying that for about
seven years now).

Thanks, A
