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
The help page makes me think that repositioning the x-labels (which
would also require repositioning or suppressing the "upper"
dendrogram) would require hacking the function, since it sets up
specific regions on the page with layout(). You should provide a
minimal example for other readers, but I'm not going to proceed
further since it is now clear that you are not just trying to move the
'xlab' which was how I interpreted your initial problem description.
[ Assuming you have suppressed the column dendrogram, it may be a
simple as changing the 1 to 3 in this line of code:
axis(1, 1:nc, labels = labCol, las = 2, line = -0.5, tick = 0,
cex.axis = cexCol)
....]

Hey David,
Thanks for answering, but can I use mtext with the heatmap.2
function? According to the description that's not one of the
arguments it takes.
It's not an argument. When someone types ?<something> it means to
look at the help page for the <something> function which will
appear if you just type ?<something> at the console.
Sorry if these questions are trivial, I'm very new with R,
basically being forced to learn it for work.
Best,
Mark Aquino

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.
?mtext
Any help with this would be greatly appreciated.
