HWAlrPlot: Plot genetic markers in additive log-ratio coordinates

Description Usage Arguments Value Author(s) References See Also Examples

View source: R/HWAlrPlot.R

Description

HWAlrPlot creates a scatter plot of the log-ratio coordinates of bi-allelic genetic markers. Hardy-Weinberg equilibrium is indicated by a straigh line in the plot.

Usage

1
HWAlrPlot(X, zeroadj = 0.5)

Arguments

X

A matrix of genotype counts (columns AA, AB, BB)

zeroadj

Zero-adjustment parameter. Zero counts in the count matrix are substituted by zeroadj which is 0.5 by default.

Value

NULL
