Hi so I have a dataframe that looks like this:

df1:

My goal is to create a venn diagram, where there are four events that makes the four circles in a venn diagram. And say if within a row, if all four events are equal to 1, then that would contribute to the inner most middle value. Whereas if there was a 1 for event 1 and event 3, I would have a value that is tallied for the area that engulfs the venn diagram ring for event 1 and 3.

I looked into using the ggvenn package and the VennDiagram approach, but neither is working in my favor and I would appreciate any help please. Thank you!

I went ahead and posted the code below for the data frame:

# Creating the df1
Name <- c("Amanda", "Emily", "George", "Baker", "Lee", "Jorge")
Event1 <- c(1,0,1,0,1,0)
Event2 <- c(1,0,0,0,1,1)
Event3 <- c(1,1,0,1,1,0)
Event4 <- c(1,1,0,0,1)
df1 <- data.frame(Name, Event1, Event2, Event3, Event4)

If you change the order of columns in your dataframe and 'convert' each Event column from "1/0" to "TRUE/FALSE" the ggvenn package works as expected, i.e.

library(tidyverse)
#install.packages("ggvenn")
library(ggvenn)
#> Loading required package: grid

Name <- c("Amanda", "Emily", "George", "Baker", "Lee", "Jorge")
Event1 <- c(1,0,1,0,1,0)
Event2 <- c(1,0,0,0,1,1)
Event3 <- c(1,1,0,1,1,0)
Event4 <- c(1,1,0,0,1, 0)
df1 <- data.frame(Event1, Event2, Event3, Event4, Name)

df1 %>%
  mutate(across(starts_with("Event"), as.logical)) %>%
  ggplot()  
  geom_venn(aes(A = Event1, B = Event2, C = Event3, D = Event4),
            set_names = Name)

I was getting an error when "Name" was the first column in the dataframe ('column 1 isn't logical') so moving that column and changing the 0/1 to TRUE/FALSE made sense.
