You know, I thought this would be fairly easy, but it wasn't really.
# define a function that extracts the value from one field
# selected by a value in another field
# define another function that equates all of the values
# get the most frequent value in fieldname2
# for the desired value in fieldname1
# now set all the values to the most frequent
for(i in 1:length(x))
