make_sample_lr_prod_activity_plots: make_sample_lr_prod_activity_plots

In saeyslab/multinichenetr: MultiNicheNet: a flexible framework for differential cell-cell communication analysis from multi-sample multi-condition single-cell transcriptomics data

make_sample_lr_prod_activity_plots

Description

make_sample_lr_prod_activity_plots Visualize the scaled product of Ligand-Receptor (pseudobulk) expression per sample, and compare the different groups. In addition, show the NicheNet ligand activities in each receiver-celltype combination.

Usage

make_sample_lr_prod_activity_plots(prioritization_tables, prioritized_tbl_oi, widths = NULL)

Arguments

prioritization_tables	Output of 'generate_prioritization_tables' or sublist in the output of 'multi_nichenet_analysis'
prioritized_tbl_oi	Subset of 'prioritization_tables$group_prioritization_tbl': the ligand-receptor interactions shown in this subset will be visualized: recommended to consider the top n LR interactions of a group of interest, based on the prioritization_score (eg n = 50; see vignettes for examples).
widths	Vector of 4 elements: Width of the LR exprs product panel, width of the scaled ligand activity panel, width of the ligand activity panel & width of the cell-type specificity panel. Default NULL: automatically defined based on nr of samples vs nr of group-receiver combinations. If manual change: example format: c(6,2,2,1)

Value

Ligand-Receptor Expression Product & Ligand Activities Dotplot/Heatmap
