Arguments

seurat_object: Seurat object name.
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().
plot_title: Plot Title.
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.
x_axis_label: Label for x axis.
y_axis_label: Label for y axis.
low_cutoff: Plot line a potential low threshold for filtering.
high_cutoff: Plot line a potential high threshold for filtering.
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
