Enter a set intersection list
Enter the information for a set intersection display.
getIntersectList(nelem,xnames=NULL,sep="+")
nelem |
The number of sets for which the intersections will be displayed. |
xnames |
The labels for the set intersections. The function creates names from combinations of the first nelem capital letters if none are given. |
sep |
The separator to use when calling paste. |
getIntersectList allows the user to manually enter the counts of set intersections rather than build this information from a matrix of data. It is probably most useful for producing an intersection diagram when the counts of the intersections are already known, or when the values are proportions rather than counts as in the example.
It is very helpful when there are large numbers of elements, as the makeIntersectList function runs very slowly.
A list of the counts of elements in the set intersections.

## Not run:
hapIntList<-
getIntersectList(3,xnames=c("hap.Pd","hap.Pt","hap.Py"))
# enter the data as follows:
# Number of elements in hap.Pd - 1: 27.586
# Number of elements in hap.Pt - 1: 20.689
# Number of elements in hap.Py - 1: 31.035
# Number of elements in hap.Pd-hap.Pt - 1: 10.345
# Number of elements in hap.Pd-hap.Py - 1: 10.345
# Number of elements in hap.Pt-hap.Py - 1: 0
# Number of elements in hap.Pd-hap.Pt-hap.Py - 1: 0
# Total number of elements - 1: 100
