Apologies for what's probably quite simple, but I'm having some problems with
sorting a data frame by the number of occurences of each level of a factor.

attributes(sort(summary(df$name)))$name = "e" "f" "g" "c" "d" "a" "b":

> sort(summary(df$name))

e f g c d a b

1 1 1 3 3 5 6

id name

8 e

17 f

20 g

4 c

11 c

19 c

6 d

9 d

10 d

1 a

5 a

12 a

14 a

15 a

2 b

3 b

7 b

13 b

16 b

18 b

Any suggestions would be greatly appreciated.

Thanks.
