geom_venn: create a venn diagram in ggplot2

In NicolasH2/ggvenn: create venn diagrams in ggplot

Description

Imports: ggplot2

Usage

geom_venn(
  setlist,
  xlim = c(0, 1),
  ylim = c(0, 1),
  numbersize = 4,
  numbercolor = "black",
  textsize = 4,
  textcolor = "black",
  fillCol = TRUE,
  borderCol = FALSE,
  fixedCoords = TRUE,
  ...
)

Arguments

setlist	list of character vectors.
xlim	vector with 2 numbers, x axis limits for the venn diagram.
ylim	vector with 2 numbers, y axis limits for the venn diagram.
textsize	integer, defining the text size of the numbers in the graph.
fillCol	boolean, should the fill color indicate the list items?
borderCol	boolean, should the border color indicate the list items?
fixedCoords	boolean, should coord_fixed be applied? If TRUE, makes the graph into a square.
...	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.

Details

the function uses geom_polygon for the dendrogram, so ... takes all arguements that geom_polygon would also take, such as color, size, alpha, etc.

Value

a ggplot2 layer objects (geom_polyon for the venn diagram) that can directly be added to a ggplot2 object

Examples

library(ggvenn)
library(ggplot2)

set1 <- rownames(subset(mtcars, mpg>18))
set2 <- rownames(subset(mtcars, qsec>18))
set3 <- rownames(subset(mtcars, cyl<5))
carset <- list(highMpg=set1, highQsec=set2, lowCyl=set3)

ggplot2::ggplot() + geom_venn(carset)
