R help - Jun 2011 - heatmap question

Hi,

I have what would seem to be a very simple problem but have been unable to find
any way to go about solving it:
I am using heatmap.2 to create a heatmap and by default the x axis label is at
the bottom of the heatmap, I simply want to move the label to the top of the
heatmap.  Any help with this would be greatly appreciated.

Thanks,
Mark

Yes I understand what ?<text> means, I meant is it possible to use this
function (as an argument) with heatmap.2,  but I learned I can use
add.expr=mtext(....) to do that.  However I'm not simply trying to add more
text to the graph but rather move the display of the x-axis labels from the
bottom of the chart to the top so the output would be more like:

1 2 3 4 5 6
--------------|1 
		   |2
		   |3
		   |4
		   |5

According to the description that's not one of the arguments it takes.

look at the help page for the <something> function which will appear if
you just type ?<something> at the console.
