a list of vectors of genes to plot jointly. Each entry in the list will be plotted
for the joint density. All entries in list must be greater than 2 features. If a named list is provided
then the names for each list entry will be incorporated into plot title if single_pdf = TRUE or
into file name if FALSE.
viridis_palette
color scheme to use.
custom_palette
color for non-expressed cells.
pt.size
Adjust point size for plotting.
file_path
directory file path and/or file name prefix. Defaults to current wd.
file_name
name suffix and file extension.
file_type
File type to save output as. Must be one of following: ".pdf", ".png", ".tiff", ".jpeg", or ".svg".
single_pdf
saves all plots to single PDF file (default = FALSE). `file_type`` must be .pdf.
output_width
the width (in inches) for output page size. Default is NULL.
output_height
the height (in inches) for output page size. Default is NULL.
dpi
dpi for image saving.
reduction
Dimensionality Reduction to use (if NULL then defaults to Object default)
combine
Create a single plot? If FALSE, a list with ggplot objects is returned.
joint
NULL. This function only supports joint = FALSE. Leave as NULL to generate plots. To iterate joint plots see function: Iterate_Plot_Density_Joint.
