Hi,
Please advice on what type of graph can be used to display the following
data set.
I have the following:
Name Class
a Class 1
a Class4
b Class2
b Class1
d Class3
d Class5
e Class4
e Class2
So each entry in name can belong to more than one class. I want to represent
the data as to see where overlaps occur that is which names are in the same
Class Name and also which names are unique to a Class. I tough a Venn
Diagram would work but this can only present numerical values for each
Class, I would like each name to be presented by a dot or *.
Hi Jurgens,
Have a look at the intersectDiagram function in the plotrix package.
This only plots the number of cases in each intersection, but it would
be possible to plot dots or asterisks or even the lower case letters as
long as there are not too many cases.
Jim
