getIntersectList {plotrix}R Documentation

Enter the information for a set intersection display

Description

Enter the information for a set intersection display.

Usage

 getIntersectList(nelem,xnames=NULL,sep="-")

Arguments

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.

Details

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.

Value

A list of the counts of elements in the set intersections.

Examples

 # this example is from a haplotype mapping problem submitted by Mao Jianfeng
 ## 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
