If df is your data frame then use:

df[sort.list(df$var3),]

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.
