VennItem provides a simple interface to generate Venn diagrams from two or three sets, listing the overlapping items as lists in the appropriate sections. The lists can be split into columns or shorterned for large sets and the plot is generated using ggplot allowing further customisations.
You can install the development version of VennItem from GitHub with:
# install.packages("pak")
pak::pak("microbialman/VennItem")Basic example showing two small sets.
library(VennItem)
sets <- list(Fruit_A = c("apple","banana","coconut","orange"), Fruit_B = c("banana","kiwi","lemon","orange"), Fruit_C = c("banana","kiwi","apple","pear","lime"))
vennItem(sets, set_label_size = 4)
Example of larger sets showing column formatting ability.
big_sets <- list(Fruit_A = c("apple","banana","durian","lychee","grapes","pear","melon"),
Fruit_B = c("banana","kiwi","satsuma","orange","lemon","lime"),
Fruit_C = c("banana","kiwi","apple","pear","coconut"))
vennItem(big_sets, ncol_items = 2)
Example of larger sets showing shortening.
big_sets <- list(Fruit_A = c("apple","banana","durian","lychee","grapes","pear","melon"),
Fruit_B = c("banana","kiwi","satsuma","orange","lemon","lime"),
Fruit_C = c("banana","kiwi","apple","pear","coconut"))
vennItem(big_sets, max_items_per_region = 2)
