Hi all,I'm trying to find an online tool in order to produce a Venn diagram. I haven't had much success with 'R' but I am open to any suggestions :) I have two text files containing gene name lists;preferably, I want to be able to simply paste these text files and then have a Venn diagram appear. Does such an online tool exist? Or can this be done with 'R?' Any help would be much appreciated.

This support site is intended to help people with questions about Bioconductor tools, rather than as a sort of open ended question answering service. Generally you will do better using something like Google for that sort of thing, assuming you use a well crafted search.

However, it's simple enough to do what you want. Assume you have two files, each containing gene names (you do say that, yes?). Further assume they are newline separated and contain a single gene name per line. Also assume they are called 'File1.txt' and 'File2.txt'.

## load relevant library
> library(gplots)
## read the files into a list, using the scan function
> flst <- lapply(c("File1.txt","File2.txt"), scan, what = "c")
## use the venn function from gplots to make the diagram
> venn(flst)
## you can add names that will be included in the Venn diagram
> names(flst) <- c("Name 1","Name 2")
> venn(flst)
