[R] from data.frame to Venn diagram

[Lara Poplarski]

Hello All,

I have a data.frame with this structure:

m <- matrix(sample(c(rep('yes', 10, replace = TRUE), rep('no', 10,
replace = TRUE), NA), 500, replace = TRUE), nrow = 100, ncol = 5)
colnames(m) <- colnames(m, do.NULL = FALSE, prefix = "col")
m <- as.data.frame(m)

I need to generate a Venn diagram from this data.frame, displaying the
various intersections of 'yes' for the different columns. Ideally, the
circle for each column should be proportional to the number of non-NA
entries.

The package "VennDiagram" (described here:
http://www.biomedcentral.com/1471-2105/12/35) can do all this.
However, I have not been able to figure out how to transform the
data.frame into the required list format.

Any suggestions on how to do this?

Many thanks,
Lara
