How do I draw a heatmap in r with two colors in a cell?

Question

[Tonny]

Hi,

I've found some genes with different types of mutation in our sequencing project. I would like to draw a figure similar to it below. Is there any packages or software could do the job? I found ComplexHeatmap could show many information but without something I need.
