VlnPlot: Single cell violin plot

In lambdamoses/SeuratBasics: Slimmed down version of Seurat

Description

Draws a violin plot of single cell data (gene expression, metrics, PC scores, etc.)

Usage

VlnPlot(
  object,
  features,
  cols = NULL,
  pt.size = 1,
  idents = NULL,
  sort = FALSE,
  assay = NULL,
  group.by = NULL,
  split.by = NULL,
  adjust = 1,
  y.max = NULL,
  same.y.lims = FALSE,
  log = FALSE,
  ncol = NULL,
  slot = "data",
  multi.group = FALSE,
  combine = TRUE
)

Arguments

object	Seurat object
features	Features to plot (gene expression, metrics, PC scores, anything that can be retreived by FetchData)
cols	Colors to use for plotting
pt.size	Point size for geom_violin
idents	Which classes to include in the plot (default is all)
sort	Sort identity classes (on the x-axis) by the average expression of the attribute being potted, can also pass 'increasing' or 'decreasing' to change sort direction
assay	Name of assay to use, defaults to the active assay
group.by	Group (color) cells in different ways (for example, orig.ident)
split.by	A variable to split the violin plots by,
adjust	Adjust parameter for geom_violin
y.max	Maximum y axis value
same.y.lims	Set all the y-axis limits to the same values
log	plot the feature axis on log scale
ncol	Number of columns if multiple plots are displayed
slot	Use non-normalized counts data for plotting
multi.group	plot each group of the split violin plots by multiple or single violin shapes see FetchData for more details
combine	Combine plots into a single patchworked ggplot object. If FALSE, return a list of ggplot objects

Value

A patchworked ggplot object if combine = TRUE; otherwise, a list of ggplot objects
