Adding more than 2 heatmaps side-by-side not working

[jantusan]

Hello,

Thank you for the useful package! I am trying to add heatmaps side by side with the + function of ComplexHeatmap, but it doesn't work if it is more than 2 heatmaps

p_heatmap = heatmap(mtcars_tidy, `Car name`, Property, Value, scale = "row") 

# works and throws the expected warning
p_heatmap + p_heatmap
#> Warning: Heatmap/annotation names are duplicated: Value

# gives an additional warning and an error
p_heatmap + p_heatmap + p_heatmap
#> Warning: Heatmap/annotation names are duplicated: Value
#> Warning: Incompatible methods ("+.AdditiveUnit", "+.InputHeatmap") for "+"
#> Error in p_heatmap + p_heatmap + p_heatmap : non-numeric argument to binary operator

is there a way to add more than 2 heatmaps side-by-side like in ComplexHeatmap?

This also fails for me:

p_heatmap + patchwork::plot_spacer()
# Error in p_heatmap + plot_spacer() :
#   non-numeric argument to binary operator
# In addition: Warning message:
# Incompatible methods ("+.InputHeatmap", "+.gg") for "+"

Sorry, for the slowness of the response I have been a little overwhelmed with work recently.

Just to mention that if someone would like to take this challenge and propose a fix, this would be more than welcome. This could be the introduction to the tidyomics project and get involved in upcoming papers!

I tried but I did not manage to replicate ComplexHeatmap strategy.

For the moment this is the solution

as_ComplexHeatmap(p_heatmap) +
as_ComplexHeatmap(p_heatmap) +
as_ComplexHeatmap(p_heatmap)
