Hi,
I just started playing w/ venneuler, and have a question about the last
method listed for creating inputs. This is the method where the source
is a matrix X, for which each column represents a set, and the
co-occurrence is defined by the rows. So, for example:
Rgames> foo
[,1] [,2] [,3] [,4] [,5]
[1,] 0 1 1 0 NA
[2,] 0 1 1 0 NA
[3,] 0 1 1 0 NA
[4,] 0 1 1 0 NA
[5,] 0 1 1 0 NA
[6,] 0 1 1 1 NA
[7,] 0 1 1 1 NA
[8,] 0 1 1 1 NA
[9,] 0 1 1 1 NA
[10,] 0 1 1 1 NA
[11,] 1 0 1 1 NA
[12,] 1 0 1 1 NA
[13,] 1 0 1 1 NA
[14,] 1 0 1 1 NA
[15,] 1 0 1 1 NA
[16,] 1 0 1 0 NA
[17,] 1 0 1 0 NA
[18,] 1 0 1 0 NA
[19,] 1 0 1 0 NA
[20,] 1 0 1 0 NA
Rgames> plot(venneuler(foo[,1:3]))
The result I get is at http://home.comcast.net/~cgwcgw2/venndiagram.pdf
I would not expect either A or B to extend outside C, and they shouldn't
overlap either.
Any ideas? So far as I can tell, the first method (define weights for
each 'overlap' region, e.g. "A&B"=.2, seems to work
correctly).
thanks
Carl
