Hi Chakravarthy,
[dont forget to Cc the list for useRs with the same Q.]
If you're trying to reuduce the isze of your row or column labels, i
think the following arguments of heatmap.2 {gplots} is what you want to
adjust- 'cexCol' and 'cexRow'.
Specifically on my question that you ask about, i found the BioC forum
helpful:
http://permalink.gmane.org/gmane.science.biology.informatics.conductor/30112
And in fact the phylotemp() function by default pretty much did exactly
what i needed, available here:
http://phylotemp.microeco.org/
However, it was pointed out to me that some times the best way to get
it just right is using more basic functions, which for heatmaps would be
image(). See:

Dear Karl Brand,
I am facing same problem as you have faced before (see appended mail below). I
am writing to you to find out whether you have found a solution !
I asked a similar question in R-forum
(http://r.789695.n4.nabble.com/How-to-save-heatmap-as-image-or-pdf-td3412542.html#a3413871).
Any pointers would be greatly appreciated
Thanks

Esteemed R user's,
I'm struggling to achieve some details of a heatmap using heatmap.2():
1. Change label locations, for both rows& columns from the default
right& bottom, to left and top.
Can this be done within heatmap.2()? Or do i need to suppress this
default behavior (how) and call a new function to relabel (what)
specifying locations?
2. Change the angle of the labels.
By default column labels are 90deg anti-clock-wise from horizontal. How
to bring them back to horizontal? Or better, rotate 45deg clock-wise
from horizontal (ie., rotate 135deg a.clock.wise from default)?
Any suggestions or pointers to helpful resources greatly appreciated,
Karl
