ggvenn (version 0.1.10)

geom_venn: Plot venn diagram as a ggplot layer object. It supports only data frame as input.

Description

Plot venn diagram as a ggplot layer object. It supports only data frame as input.

Usage

geom_venn(
  mapping = NULL,
  data = NULL,
  stat = "identity",
  position = "identity",
  ...,
  set_names = NULL,
  show_percentage = TRUE,
  digits = 1,
  label_sep = ",",
  count_column = NULL,
  show_outside = c("auto", "none", "always"),
  auto_scale = FALSE,
  fill_color = c("blue", "yellow", "green", "red"),
  fill_alpha = 0.5,
  stroke_color = "black",
  stroke_alpha = 1,
  stroke_size = 1,
  stroke_linetype = "solid",
  set_name_color = "black",
  set_name_size = 6,
  text_color = "black",
  text_size = 4
)

Value

The ggplot object to print or save to file.

Arguments

mapping

Set of aesthetic mappings created by aes(). If specified and inherit.aes = TRUE (the default), it is combined with the default mapping at the top level of the plot. You must supply mapping if there is no plot mapping.

data

A data.frame or a list as input data.

stat

The statistical transformation to use on the data for this layer, as a string.

position

Position adjustment, either as a string naming the adjustment (e.g. "jitter" to use position_jitter), or the result of a call to a position adjustment function. Use the latter if you need to change the settings of the adjustment.

...

Other arguments passed on to layer(). These are often aesthetics, used to set an aesthetic to a fixed value, like colour = "red" or size = 3. They may also be parameters to the paired geom/stat.

set_names

Set names, use column names if omitted.

show_percentage

Show percentage for each set.

digits

The desired number of digits after the decimal point

label_sep

separator character for displaying elements.

count_column

Specify column for element repeat count.

show_outside

Show outside elements (not belongs to any set).

auto_scale

Allow automatically resizing circles according to element counts.

fill_color

Filling colors in circles.

fill_alpha

Transparency for filling circles.

stroke_color

Stroke color for drawing circles.

stroke_alpha

Transparency for drawing circles.

stroke_size

Stroke size for drawing circles.

stroke_linetype

Line type for drawing circles.

set_name_color

Text color for set names.

set_name_size

Text size for set names.

text_color

Text color for intersect contents.

text_size

Text size for intersect contents.
