[R] How do you sort a data frame on a selection of columns?

This is what to start with:

Data Frame      A          B	C	D
		c1	4	y	5
		c3	6	d	7
		c1	5	t	6

Now sort on A then C

This is what to end with:

Data Frame     A          B	C	D
		c1	5	t	6
		c1	4	y	5
		c3	6	d	7

I assume it is something like this:

attach(DF)
sort(DF,partial=c(A,C))

Thanks in advance.
