Hi there

I have a data frame with about 65,000 rows and 8 variables.  I am trying to 
get rid of the double entries of a factor variable "ID" so I can get a 
unique observation for each ID

I tried:

>dupl_unique.data.frame(data[ID,]) #I obtain a data frame with 21,547 
>observations..so far so good, but then when I check for duplicates

  6836 14711

Meaning that I am still getting 14,711 duplicates!

I tried changing the ID type to integer and repeated the process but I got 
dentical results....what am I missing?
