netAnalysis_diff_signalingRole_scatter | R Documentation |
This scatter plot shows the differential signaling roles (dominant senders (sources) or receivers (targets) in a 2D space.
x-axis and y-axis are respectively the differential outgoing or incoming communication probability associated with each cell group. Dot colors indicate different cell groups. Dot shapes indicate different categories of cell groups if 'group“ is defined.
Positive values indicate the increase in the second dataset while negative values indicate the increase in the first dataset

object |
A merged CellChat object of a list of CellChat objects |
color.use |
defining the color for each cell group |
comparison |
an index vector giving the two datasets for comparison |
signaling |
a char vector containing signaling pathway names. signaling = NULL: Signaling role analysis on the aggregated cell-cell communication network from all signaling pathways |
signaling.exclude |
signaling pathways to exclude |
idents.exclude |
cell groups to exclude. This is useful when zooming into the small changes |
slot.name |
the slot name of object that is used to compute centrality measures of signaling networks |
group |
a vector to categorize the cell groups, e.g., categorize the cell groups into two major categories: immune cells and fibroblasts |
dot.size |
the size of the symbol |
point.shape |
point shape when group is not NULL |
label.size |
font size of the text |
dot.alpha |
transparency |
x.measure |
The measure used as x-axis. This measure should be one of 'names(slot(object, slot.name)$centr[[1]])' computed from 'netAnalysis_computeCentrality' Default = "outdeg" is the weighted outgoing links (i.e., Outgoing interaction strength). If setting as "outdeg_unweighted", it represents the total number of outgoing signaling. |
y.measure |
The measure used as y-axis. This measure should be one of 'names(slot(object, slot.name)$centr[[1]])' computed from 'netAnalysis_computeCentrality' Default = "indeg" is the weighted incoming links (i.e., Incoming interaction strength). If setting as "indeg_unweighted", it represents the total number of incoming signaling. |
xlabel |
label of x-axis |
ylabel |
label of y-axis |
title |
main title of the plot |
font.size |
font size of the text |
font.size.title |
font size of the title |
do.label |
label the each point |
show.legend |
whether show the legend |
show.axes |
whether show the axes |
