In weitingwlin/vennchart: Making Venn/Eular charts

0. Download, install, library the package

# install.packages("devtools")
 library(devtools)
# install the package from github
 install_github("vennchart", "weitingwlin")
 library(vennchart)

1. Prepare mock data

rm(list =ls())
co_A <- 8 # including pure and overlapping parts
co_B <- 12
co_C <- 3
co_AB <- 1.9 # overlaping parts
co_BC <- 0.5
co_AC <-1

2. Examples

2.1 two-circle Venn chart (with default)

Q <- vennChart(A_all = co_A, B_all = co_B, AandB = co_AB)

2.2 three-circle Venn chart (more parameters)

Q <- vennChart(A_all = co_A, B_all = co_B, C_all = co_C,
                AandB = co_AB, AandC = co_AC, BandC = co_BC,
               # rename element A,B,C
               # rewrite format
               names = c("a", "b", "c"), connect = "\n(", unit = "%)", 
               # adjust text positions
               textadj = c(1.3, 0.3),
               # make the text relatively bigger
               cex = 1.3,
               # make the frame relatively smaller
               frameadj = 1.2)
