I have a data.frame with the following: ID Species Count 1 A 3 1 B 2 1 E 12 2 A 13 2 C 5 2 F 4 3 B 5 3 D 3 I need it in this format: ID A B C D E F 1 3 2 0 0 12 0 2 13 0 5 0 0 4 3 0 5 0 3 0 0
Assuming the dataframe is called dtt: > xtabs(Count ~ ID + Species, data=dtt) Species ID A B C D E F 1 3 2 0 0 12 0 2 13 0 5 0 0 4 3 0 5 0 3 0 0
