I dont get it:
> is.vector(c(mydf[1]))
[1] TRUE
> unique(c(mydf[1]))
Error in unique(c(mydf[1])) : unique() applies only to vectors

Is it a vector or not? This stuff is driving me nuts. I'm simply trying
to convince R that my grouping vector is actually a vector so that
unique will work. Its just a vector of numbers, so why shouldnt it work?
