Plotting crashed for small matrix with 0 and 1

[ievarau]

Hei,

I encountered an error, where plotting crashes. I run pairwise module to compute Jaccard statistic. It results in a following matrix:

HUMAN_IRF4 HUMAN_IRF3
HUMAN_IRF4 1.0 0.0
HUMAN_IRF3 0.0 1.0

But then I get this error. I assume it cannot handle the zeroes.

Not a big deal for me as long as I have the matrix, but I would be curious to know the true reason, why this does not work.

Thanks!
Best,

And one additional comment. When Jaccard statistic is equal to 0, in the heatmap it appears as white. Even though the palette is going from dark blue to dark red with white representing 0.5.
