I have 25 lists of genes.
On each list, there are anywhere from 1-50 genes
I want to process these lists to find, between these 25 lists, which genes show up most frequently.
Can anyone help?
What I have tried on R:
Loading all 25 lists, and then
However: when inputting 25 lists, it usually gives me a null because no single gene appears on all 25 lists.
My aim is to have a result where I have a list of genes listed by frequency of appearance within these 25 lists.
