[R] heatmap.2

[John Celniker]

Hi folks,

I have been working with the ellipse library and trying to use the
heatmap.2 function. I have called the function as follows

hh <- heatmap.2(DATA, Rowv= F,  trace = "none",
       colsep=seq(1, 4), rowsep = seq(1,dim(GENES)[1]),  col =
brewer.pal(9,
"YlOrRd"),
       lmat=rbind( c(3, 4,0), c(2,1,1)), lwid=c(0.2, 1,0.5 ), lhei= c
(0.18,0.5),
       breaks = br1)

where DATA is a numeric matrix and
>br1
 [1] 0.0000000 0.5337751 1.0675502 1.6013253 2.1351003 2.6688754
3.2026505 3.7364256 4.2702007
[10] 4.8039758

when I try to change the breaks by using br2, which is
> br2
 [1] 0.0000000 0.5337751 1.0675502 1.6013253 2.1351003 3.0000000
3.5000000 4.0000000 4.5000000
[10] 4.8039758

I get the correct heatmap representation but the color key does not
correctly update to reflect the changes in breaks even though the
superimposed histogram is also corrected.

I looked at the souce code for heatmap.2. The relevant section of the
function that outputs the color key begins at line 324.  Any
suggestions to fix this problem?

Thanks for any help on this!
