ggVennDiagram
‘ggVennDiagram
’ enables fancy venn plot with 2-4 sets and generates
publication quality figure. It is the first software that can
automatically fill different colors to each part of a venn diagram.
Installation
You can install the released version of ggVennDiagram from CRAN with (under evaluation in CRAN):
install.packages("ggVennDiagram")
And the development version from GitHub with:
# install.packages("devtools")
devtools::install_github("gaospecial/ggVennDiagram")
Example
ggVennDiagram
maps the fill color of each region to quantity, allowing
us to visually observe the differences between different parts.
library(ggVennDiagram)
genes <- paste("gene",1:1000,sep="")
set.seed(20190708)
x <- list(A=sample(genes,300),B=sample(genes,525),C=sample(genes,440),D=sample(genes,350))
# four dimension venn plot
ggVennDiagram(x)
# three dimension venn plot
ggVennDiagram(x[1:3])
# two dimension venn plot
ggVennDiagram(x[1:2])
ggVennDiagram
return a ggplot object, which can be further modified
with ggplot
functions.
library(ggplot2)
ggVennDiagram(x) + scale_fill_gradient(low="blue",high = "red")
#> Scale for 'fill' is already present. Adding another scale for 'fill',
#> which will replace the existing scale.
ggVennDiagram(x,lty="dashed",color="black",size=2) + scale_fill_gradient(low="white",high = "red")
#> Scale for 'fill' is already present. Adding another scale for 'fill',
#> which will replace the existing scale.
ggVennDiagram
now support 2-4 dimension venn plot. The generated
figure is generally ready for publish. The main function
ggVennDiagram()
will check how many items in the first paramenter and
call corresponding function automatically.
The parameter category.names
reprents set names. And the parameter
label
can label how many items are included in each parts.
ggVennDiagram(x,category.names = c("Stage 1","Stage 2","Stage 3", "Stage4"))
ggVennDiagram(x,category.names = c("Stage 1","Stage 2","Stage 3", "Stage4"), label = NULL)
