Venn.diagram code help

[abiconnor]

I am trying to plot a venn diagram of common genes from separate lists, but the output is incorrect as I know there should be overlaps. I have spent quite a few hours looking for help on this topic but I cannot solve it - please could someone look at my code and advise?

install.packages("VennDiagram")
library(VennDiagram)

#importing data as .txt files

tumour1 <- read.table("25_1_fs_insertions.txt", header = TRUE)
tumour2 <- read.table("25_2_fs_insertions.txt", header = TRUE)
tumour3 <- read.table("25_3_fs_insertions.txt", header = TRUE)

#combining the data as a list
combined <- list(A = tumour1, B = tumour2, C = tumour3)
combined

#trying to plot the data as a venn diagram
venn.diagram(x=combined,
category.names = c("Tumour 1", "Tumour 2", "Tumour 3"),
filename = '#25_venn_diagram.png', output = TRUE)

Hi, none of us have your data so can't run your code properly. You should provide a reproducible example:

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…

Perhaps your data doesn't overlap?
