[R] Vizualization of points within sets

[Sigbert Klinke]

Hi,

> I have a visualization question regarding sets. My problem is as follows:

I would define a distance matrix for the points as

d_ij = 0 if the points in the same set and 1 if not

In case that points can be in more than two sets use an more appropriate
distance measure, e.g. Jaccard etc. Then run a nonmetric
(two-dimensional) multidimensional scaling (package: MASS, function:
isoMDS) to determine the point positions. But I'am not sure that it will
be easy to draw the set borders.

Yours sincerely
