I have four csv files with the first row with gene name

and the second row with rsIDs.

I attached 4 files to the variables. and I want to make the venn diagram with existing rsIDs.

How should I start?? I am so new to this R....

I don't know of any software on Bioconductor that is specific for drawing Venn diagrams, so this is probably not the place to ask. But do note that a Google search for 'venn R' turned up several choices, most of which are likely to have a vignette that explains how to use them.
