Hi,
I wanted to draw a heatmap with some horizontal lines. For example:
#------ code ------
mat <- matrix(-1:1,7,9)
heatmap.2(mat,Rowv=NA,trace = 'none',key=F)
#----end code -----
In this heatmap, I want to subgroup the rows. For instance, I would like to group rows 5,6
& 7 together, and would draw a black line between rows 4 & 5 to demarcate the group.
Similarly, I want to group rows 3 & 4 in one group, and would like to put a black line
between rows 2 & 3.
I guess I'm looking for the 'hline' parameter or something, but couldn't find
it in the documentation.
Any help would be appreciated!
