Dear all,

I have a date frame like this:

X Y Z

22	24	4.3
2.3	3.4	5.3

.....
....

57.2 23.4 34

What my purpose is: to sort the data frame by either X, Y or Z. sample output is (sorted by X) :

X Y Z

2.3  3.4  5.3

.....
......

22 24 4.3
...
57.2 23.4 34

I have no idea how to use sort, order or rank functions. Please help me out. Thanks!

Leaf
