Problem with multy level sorting

Hi all
I have a dataframe like I coppied below

ff
      a      b      d
1    10     5       7
2    20     4       9
3     3     8       10
4     5     6        8
5     6     3        5
6    73    7        3
7    45    28      9
8    3      2       8

while I am trying to sort multy coloums  at once I am not able to  
get that
like ina order of   first column "a" next column "d" after that  
column "b"
here I tried with

o <- order(a,d,b)
a, b and d are not objects. They are columns within ff.

  with( ff, order(a,b,d))
#[1] 8 3 4 5 1 2 7 6
but it returns an error
can any one help me to sort this multy-columns atonce
The ordering of that dataframe would be (almost) uniquely determined  
by ordering on the first column. Even the one duplicate (3) gets  
resolved with reference to the second column.

ff[with(ff, order(a,b,d)), ]

    a  b  d
8  3  2  8
3  3  8 10
4  5  6  8
5  6  3  5
1 10  5  7
2 20  4  9
7 45 28  9
6 73  7  3

thanks in advance
