Problem merging data frames and duplicates

William Michels 
Hi Frank,

It looks like you're very close. I think you want:

unique(merge(x, y, by = 1, all=T))

Gabor Grothendieck's sqldf package is very useful if you're more
comfortable with SQL-type syntax, see:

Best Regards,

William (Bill) Michels, Ph.D.
