getCoord: Computes coordinates of a canonical point

Description

This function calculates the x and y coordinates of a canonical point on BAF-LRR plot.

Usage

getCoord(p, x0, y0, nn, nb, nt)

Arguments

p

numeric, proportion of aneuploid genome for a DNA segment

x0

numeric, x coordinate for the Origin Cluster

y0

numeric, y coordinate for the Origin Cluster

nn

integer, ploidy indicator. 1, diploid; 2, tetraploid; 3, hexaploid

nb

integer, number of minor alleles

nt

integer, number of total alleles

Value

A list of x and y coordinates.

Examples

x0=0.05
y0=0.2
p=0.8
