[R] venn.diagram, error message: Incorrect number of elements

[Sarah Goslee]

The venn.diagram() function in the package VennDiagram only works with
sizes up to 5.

That isn't horribly clear from the help file, but quite explicit in the code:

    if (0 == length(x) | length(x) > 5) {
        stop("Incorrect number of elements.", call. = FALSE)
    }

If you really need 6, you could presumably look at the way that
venn.diagram() works and add in your own 6-handling code.
