Dear R helpers,
I have a data set with 4 types (W, C, E & S). Now I have values for all
types plus all possible combinations (the order is unimportant): W, C,
WC, E, WE, CE, WCE, S, WS, CS, WCS, ES, WES, CES & WCES. Ideally I would
like to represent everything in one graph and as concise as possible.
Drawing 4 circles and depicting it as overlap just gives me 13 out of
the 15 possibilities needed (as e.g. depicted here
http://www.psy.ritsumei.ac.jp/~akitaoka/classic9e.html in the graph
"Four circles surrounding illusion").
Does anybody has a nice solution, ideally with a possible solution in R?
Hi Johannes,
If you want to display the intersections between your 4 types, you might
find that intersectDiagram in the plotrix package will serve your
purpose. It departs from the Venn diagram approach to display an array
of rectangles, the widths of which are proportional to the number of
members of each set and intersection.
