[R] order by decerasing 1st variable and increasing 2nd variable

[Daniel Brewer]

Hello,

I have a data.frame which I would like to sort with the primary key
decreasing while the secondry key is increasing e.g.

x <- data.frame(One=c(1,1,1,2,2,3,4,5),Two=c(2,3,1,2,3,3,3,3))

I would like to order it so it looks like this:

  One Two
8   5   3
7   4   3
6   3   3
4   2   2
5   2   3
3   1   1
1   1   2
2   1   3

i.e. primarily decreasing in the 1st column but if there is a tie
increasing in the second column.

Is this possible?  I can not find anything in order that seems to
support this.  I would have thought,

x[order(x$One,x$Two,decreasing=c(T,F)),]

would do it but it doesn't.

Thanks

Dan
