Highlight cells on heatmap

Question

I'm actually using the heatmap.2 package from R

and the idea is that I have a matrix as :

  COL1 COL2 COL3 COL4
A    1    0    0    1
B    1    0    1    1
C    1    0    1    0
D    0    1    1    0

which gives me a heatmap such as :

heatmap.2(as.matrix(matrix), trace="none",density.info="none",key = F)

But now I would like to know if it is possible with heatmap.2 from this matrix :

matrix_hilight_coordonates

 COL1 COL2 COL3 COL4
A    A    B    B    B
B    A    A    A    A
C    A    A    A    B
D    B    B    B    B

with the same dimension to:

• highlight cells where there is a B as in example A

OR

• hatch cells where there is a B as in example B

here is a related question : Highlight Subset Cells From Heatmap By Row/Col Index

the problem is that they do not go from a specific df in order to highlight the cells.

Thank you very much for your time and help
