[R] sorting data frame

[Patrick E. McKnight]

Greetings,

I hope this isn't obvious but I've read through the FAQ and the various 
other R/S books I have and I cannot, for the life of me, figure out how 
to sort a data frame by a specific variable.  Suppose I have a four 
variable data.frame x and the variables are var1, var2, var3, var4.  I 
want to sort on say var3 simply for display purposes.  How can this be 
accomplished?  Thanks in advance for any hints, RTFM (the exact one 
please), or any other useful pointers.

BTW, I'm using version 1.4 on Linux-Mandrake FWIW.
