In eisascience/scCustFx: single-cell custom fxs Package

Plot Gene Expression in Seurat Object

Description

This function generates a violin plot or pie chart for the expression of a specified gene in a Seurat object, based on a given threshold.

Usage

plotGeneExpression(
  serObj,
  gene,
  threshold = 0.5,
  groupBy = "RNA_snn_res.0.4",
  doPie = FALSE,
  col_vector = col_vector
)

Arguments

gene	The name of the gene for which expression is to be plotted.
threshold	The expression threshold for selecting cells (default is 0.5).
groupBy	The variable by which the data is grouped (default is "RNA_snn_res.0.4").
doPie	Logical, if TRUE, a pie chart is generated instead of a violin plot (default is FALSE).
SerObj	A Seurat object containing single-cell RNA-seq data.
