Arguments

seurat_object

Seurat object name.

group.by

Name of one or more metadata columns to group (color) cells by (for example, orig.ident); default is the current active.ident of the object.

feature_cutoffs

Numeric vector of length 1 or 2 to plot lines for potential low/high threshold for filtering.

UMI_cutoffs

Numeric vector of length 1 or 2 to plot lines for potential low/high threshold for filtering.

mito_cutoffs

Numeric vector of length 1 or 2 to plot lines for potential low/high threshold for filtering.

mito_name

The column name containing percent mitochondrial counts information. Default value is "percent_mito" which is default value created when using Add_Mito_Ribo_Seurat().

pt.size

Point size for plotting

plot_median

logical, whether to plot median for each ident on the plot (Default is FALSE).

median_size

Shape size for the median is plotted.

plot_boxplot

logical, whether to plot boxplot inside of violin (Default is FALSE).

colors_use

vector of colors to use for plot.

x_lab_rotate

Rotate x-axis labels 45 degrees (Default is TRUE).

y_axis_log

logical. Whether to change y axis to log10 scale (Default is FALSE).

raster

Convert points to raster format. Default is NULL which will rasterize by default if greater than 100,000 total points plotted (# Cells x # of features).

ggplot_default_colors

logical. If colors_use = NULL, Whether or not to return plot using default ggplot2 "hue" palette instead of default "polychrome" or "varibow" palettes.

color_seed

random seed for the "varibow" palette shuffle if colors_use = NULL and number of groups plotted is greater than 36. Default = 123.

...

Extra parameters passed to VlnPlot.

Value

A ggplot object
