[R] sorting table output

[Erin Hodgess]

Dear R People:

Suppose I have the following output:

> table(xx)
xx
 A  C  G  T
13 12 10 15


I would like to have the output sorted in descending order by "height"
or frequency.

But when I do the following:

> rev(table(xx))
xx
 T  G  C  A
15 10 12 13
>

the output is sorted by the names rather than the frequency.

Any suggestions, please?

Thanks in advance,
Erin
