Binary heatmap using R
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")

Use heatmap.2 and add na.color = "light blue".

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
