Binary heatmap using R

Question

[martin.gallix]

Hi everybody.

I would like to do a binary heatmap on R, made only of 0/1, but if I have lines with only zero values the graph does not shown them and I see a blank space.

This is my code:

heatmap(x , Rowv = NA, Colv = NA, col = c("light blue", "red"), xlab = "xlab" , ylab="ylab"  , main = "title")

What is the error message you are receiving? Can you also provide an example of your data, cannot visualise it based on your description.

i did not have any error, just my graph is blanked instead of being coloured. For example

0000 = all blue 0001 = 3 blue 1 red 1111 = 4 red

But the first line is blank in my resulting graph
