How can I extract all different rows from a dataframe in R

Question

I have a table with repeated rows and I need to extract all different rows from that table. The first 10 lines of the table are..

        m         t              d               
 [1,] "ausente" "bovino"       "bife/costeleta"
 [2,] "ausente" "bovino"       "inteiro"       
 [3,] "ausente" "bovino"       "miudezas"      
 [4,] "ausente" "bovino"       "peca"          
 [5,] "ausente" "bovino"       "peq_peca"      
 [6,] "ausente" "bovino"       "preparado"     
 [7,] "ausente" "bovino"       "semi-preparado"
 [8,] "ausente" "bovino/suino" "bife/costeleta"
 [9,] "ausente" "bovino/suino" "inteiro"       
 [10,] "ausente" "bovino/suino" "miudezas"

Do you want unique rows to be extracted? – akrun Dec 19 '14 at 10:56 — akrun, Dec 19 '14 at 10:56
try `mytable[!duplicated(mytable),]` – Cath Dec 19 '14 at 10:56 — Cath, Dec 19 '14 at 10:56
