Arguments

data	A data frame.
in_form	A character string indicating the datatype of the input data. Possible values are "long", "wide", "list", "venn" or NULL. "long" indicates the data is in long format. "wide" indicates the data is in wide format. "list" indicates the data is a list. "venn" indicates the data is a VennPlotData object. "auto" indicates the function will detect the datatype of the input data. A long format data would look like: group_by id_by A a1 A a2 B a1 B a3 ... A wide format data would look like: A B TRUE TRUE TRUE FALSE FALSE TRUE ... A list format data would look like: list(A = c("a1", "a2"), B = c("a1", "a3"))
split_by	The column(s) to split data by and plot separately.
split_by_sep	The separator for multiple split_by columns. See split_by
group_by	Columns to group the data for plotting For those plotting functions that do not support multiple groups, They will be concatenated into one column, using group_by_sep as the separator
group_by_sep	The separator for multiple group_by columns. See group_by
id_by	A character string specifying the column name of the data frame to identify the instances. Required when group_by is a single column and data is a data frame.
label	A character string specifying the label to show on the Venn diagram. Possible values are "count", "percent", "both", "none" and a function. "count" indicates the count of the intersection. "percent" indicates the percentage of the intersection. "both" indicates both the count and the percentage of the intersection. "none" indicates no label. If it is a function, if takes a data frame as input and returns a character vector as label. The data frame has columns "id", "X", "Y", "name", "item" and "count".
label_fg	A character string specifying the color of the label text.
label_size	A numeric value specifying the size of the label text.
label_bg	A character string specifying the background color of the label.
label_bg_r	A numeric value specifying the radius of the background of the label.
fill_mode	A character string specifying the fill mode of the Venn diagram. Possible values are "count", "set", "count_rev". "count" indicates the fill color is based on the count of the intersection. "set" indicates the fill color is based on the set of the intersection. "count_rev" indicates the fill color is based on the count of the intersection in reverse order. The palette will be continuous for "count" and "count_rev". The palette will be discrete for "set".
fill_name	A character string to name the legend of colorbar.
palette	A character string specifying the palette to use. A named list or vector can be used to specify the palettes for different split_by values.
palcolor	A character string specifying the color to use in the palette. A named list can be used to specify the colors for different split_by values. If some values are missing, the values from the palette will be used (palcolor will be NULL for those values).
alpha	A numeric value specifying the transparency of the plot.
theme	A character string or a theme class (i.e. ggplot2::theme_classic) specifying the theme to use. Default is "theme_this".
theme_args	A list of arguments to pass to the theme function.
title	A character string specifying the title of the plot. A function can be used to generate the title based on the default title. This is useful when split_by is used and the title needs to be dynamic.
subtitle	A character string specifying the subtitle of the plot.
legend.position	A character string specifying the position of the legend. if waiver(), for single groups, the legend will be "none", otherwise "right".
legend.direction	A character string specifying the direction of the legend.
combine	Whether to combine the plots into one when facet is FALSE. Default is TRUE.
nrow	A numeric value specifying the number of rows in the facet.
ncol	A numeric value specifying the number of columns in the facet.
byrow	A logical value indicating whether to fill the plots by row.
seed	The random seed to use. Default is 8525.
axes	A string specifying how axes should be treated. Passed to patchwork::wrap_plots(). Only relevant when split_by is used and combine is TRUE. Options are: 'keep' will retain all axes in individual plots. 'collect' will remove duplicated axes when placed in the same run of rows or columns of the layout. 'collect_x' and 'collect_y' will remove duplicated x-axes in the columns or duplicated y-axes in the rows respectively.
axis_titles	A string specifying how axis titltes should be treated. Passed to patchwork::wrap_plots(). Only relevant when split_by is used and combine is TRUE. Options are: 'keep' will retain all axis titles in individual plots. 'collect' will remove duplicated titles in one direction and merge titles in the opposite direction. 'collect_x' and 'collect_y' control this for x-axis titles and y-axis titles respectively.
guides	A string specifying how guides should be treated in the layout. Passed to patchwork::wrap_plots(). Only relevant when split_by is used and combine is TRUE. Options are: 'collect' will collect guides below to the given nesting level, removing duplicates. 'keep' will stop collection at this level and let guides be placed alongside their plot. 'auto' will allow guides to be collected if a upper level tries, but place them alongside the plot if not.
design	Specification of the location of areas in the layout, passed to patchwork::wrap_plots(). Only relevant when split_by is used and combine is TRUE. When specified, nrow, ncol, and byrow are ignored. See patchwork::wrap_plots() for more details.
...	Additional arguments.

Value

A combined ggplot object or wrap_plots object or a list of ggplot objects

Examples
