make_ligand_activity_plots
Visualize the ligand activities (normal and scaled) of each group-receiver combination
make_ligand_activity_plots(prioritization_tables, ligands_oi, contrast_tbl, widths = NULL)
prioritization_tables |
Output of 'generate_prioritization_tables' or sublist in the output of 'multi_nichenet_analysis' |
ligands_oi |
Character vector of ligands for which the activities should be visualized |
contrast_tbl |
Table to link the contrast definitions to the group ids. |
widths |
Vector of 2 elements: Width of the scaled ligand activity panel, width of the ligand activity panel. Default NULL: automatically defined based number of group-receiver combinations. If manual change: example format: c(3,2) |
Heatmap of ligand activities (normal and scaled) of each group-receiver combination
