Communication Frequency heatmap plot

Usage

heat_freq(liana_res, ...)

Arguments

liana_res

aggregated liana results (preferably truncated to some threshold)

...

Arguments passed on to liana_heatmap

mat: Diagonal celltype-celltype matrix to be plotted. In theory, any metric deemed meaningful between cell pairs can be plotted.
font_size: base font_size - other fontsizes are relative to this one
grid_text: logical whether to display grid text or not
name: name of the heatmap. By default the heatmap name is used as the title of the heatmap legend.
row_title: Row tittle
column_title: Column tittle

Details

This plot was inspired by CellPhoneDB and also CellChat's heatmap design. It makes the assumption that the number of interactions inferred between cell types is informative of the communication events occurring in the system as a whole. This is a rather strong assumption limited by the arbitrarily filtered interactions Thus, I suggest that one limits any conclusions, unless supported by complimentary information, such as biological prior knowledge.
