Hello!
I have this problem: I want to create a Venn's diagram with three lists of
genes'names. The first is all the genome, the second a subset of it comprising
all mitochondrial genes, and the third including all genes that correlate with
a given gene.
This is what I do:
library(gplots)
A<-read.delim("F:/.../mito genes just names.txt")
B<-read.delim("F:/.../My gene all cors names.txt")
C<-read.delim("F:/.../all genes names.txt")
input<-list(A,B,C)
venn(input)
However, the output is empty, being no number inside each intersection. I think
the issue lyes in the non-numeric nature of the list, but I don't know if a
solution for this exists...
Hi Gabriele,
As I don't have the data, I can't be sure, but are the names consistent
across the three files? That is, I suspect that there may be prefixes or
suffixes that designate different classes (e.g. "m" for mitochondrial).
Jim
