Arguments

scdata: single-cell data. Must be a SingleCellExperiment object.
cell_type1: cell type 1
cell_type2: cell type 2
celltype_key: vector holding the celltype_key for each cell or column name of scdata's metadata. MUST match cpdb's columns
means: object holding means.txt from cpdb output
pvals: object holding pvals.txt from cpdb output
deconvoluted: object holding deconvoluted.txt from cpdb output
keep_significant_only: logical. Default is FALSE. Switch to TRUE if you only want to plot the significant hits from cpdb.
splitby_key: column name in the metadata/coldata table to split the spots by. Can only take columns with binary options. If specified, name to split by MUST be specified in the meta file provided to cpdb prior to analysis.
standard_scale: logical. scale the expression to range from 0 to 1. Default is TRUE
gene_symbol_mapping: default = NULL.column name for rowData in sce holding the actual gene symbols if row names aren't gene symbols
frac: default = 0.1. Minimum fraction of celtypes expressing a gene in order to keep the interaction. Gene must be expressesd >= `frac` in either of the pair of celltypes in order to keep.
remove_self: default = TRUE. Remove self-self arcs.
desiredInteractions: default = NULL. Specific list of celltype comparisons e.g. list(c('CD4_Tcm', 'cDC1'), c('CD4_Tcm', 'cDC2')). Also accepts a dataframe where first column is celltype 1 and 2nd column is celltype 2.
degs_analysis: if is CellPhoneDB degs_analysis mode.
directional: Whether links have directions. 1 means the direction is from the first column in df to the second column, -1 is the reverse, 0 is no direction, and 2 for two directional.
alpha: transparency for links
edge_colors: vector of colors for links
grid_colors: vector of colors for grids
show_legend: whether or not to show the legend
legend.pos.x: x position of legend
legend.pos.y: y position of legend
...: passes arguments plot_cpdb
