[R] heatmap.2 - change column & row locations; angle / rotate

[Karl Brand]

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
