ggvenn (version 0.1.19)

ggvenn: Plot venn diagram as an independent function. It supports both data frame and list as input.

Description

Plot venn diagram as an independent function. It supports both data frame and list as input.

Usage

ggvenn(
  data,
  columns = NULL,
  element_column = NULL,
  show_elements = FALSE,
  show_set_totals = "none",
  show_stats = c("cp", "c", "p"),
  show_counts = TRUE,
  show_percentage = TRUE,
  digits = 1,
  label_sep = ",",
  count_column = NULL,
  show_outside = c("auto", "none", "always"),
  auto_scale = FALSE,
  fill_color = default_color_list,
  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,
  comma_sep = FALSE,
  padding = 0.2,
  max_elements = 6,
  text_truncate = TRUE
)

Value

The ggplot object to print or save to file.

Arguments

data

A data.frame or a list as input data.

columns

A character vector use as index to select columns/elements.

element_column

A single character value use as column name to select elements. It is only allowed when data is a data.frame.

show_elements

Show set elements instead of count/percentage.

show_set_totals

Show total count (c) and/or percentage (p) for each set. Pass a string like "cp" to show both. Any other string like "none" to hide both.

show_stats

Show count (c) and/or percentage (p) for each set. Pass a string like "cp" to show both. Any other string like "none" to hide both.

show_counts

Show count for each set.

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). Options: "auto", "none", "always".

auto_scale

Allow automatically resizing circles according to element counts (only for 2-set diagrams).

fill_color

Filling colors in circles. Can be a single color or a vector of colors for each set.

fill_alpha

Transparency for filling circles. Can be a single value or a vector for each set.

stroke_color

Stroke color for drawing circles. Can be a single color or a vector of colors for each set.

stroke_alpha

Transparency for drawing circles. Can be a single value or a vector for each set.

stroke_size

Stroke size for drawing circles. Can be a single value or a vector for each set.

stroke_linetype

Line type for drawing circles. Can be a single value or a vector for each set.

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.

comma_sep

Whether to use comma as separator for displaying numbers.

padding

Padding for the plot. Change this to allow longer labels to be displayed.

max_elements

Maximum number of elements to display when show_elements=TRUE.

text_truncate

Whether to truncate text when elements exceed max_elements.

library(ggvenn)

# use list as input
a <- list(A = 1:5, B = 4:9, C = c(2:3, 8:12), D = c(1, 5, 9))
ggvenn(a, c("A", "B"))
ggvenn(a, c("A", "B", "C"))
ggvenn(a)

# use data.frame as input
d <- dplyr::tibble(value   = c(1,     2,     3,     5,     6,     7,     8,     9),
            `Set 1` = c(TRUE,  FALSE, TRUE,  TRUE,  FALSE, TRUE,  FALSE, TRUE),
            `Set 2` = c(TRUE,  FALSE, FALSE, TRUE,  FALSE, FALSE, FALSE, TRUE),
            `Set 3` = c(TRUE,  TRUE,  FALSE, FALSE, FALSE, FALSE, TRUE,  TRUE),
            `Set 4` = c(FALSE, FALSE, FALSE, FALSE, TRUE,  TRUE,  FALSE, FALSE))
ggvenn(d, c("Set 1", "Set 2"))
ggvenn(d, c("Set 1", "Set 2", "Set 3"))
ggvenn(d)

# set fill color
ggvenn(d, c("Set 1", "Set 2"), fill_color = c("red", "blue"))

# hide percentage
ggvenn(d, c("Set 1", "Set 2"), show_stats = "c")

# change precision of percentages
ggvenn(d, c("Set 1", "Set 2"), digits = 2)

# show elements instead of count/percentage
ggvenn(a, show_elements = TRUE)
ggvenn(d, show_elements = TRUE, element_column = "value")
