HWGenotypePlot: Scatter plot of the genotype frequencies

In HardyWeinberg: Statistical Tests and Graphics for Hardy-Weinberg Equilibrium

Scatter plot of the genotype frequencies

Description

HWGenotypePlot makes a scatterplots of the AB or BB frequency versus the AA frequency and represents a blue curve indicating the Hardy-Weinberg equilibrium condition.

Usage

HWGenotypePlot(X, plottype = 1, xlab = expression(f[AA]), ylab =
ifelse(plottype == 1, expression(f[AB]), expression(f[BB])), asp = 1,
pch = 19, xlim = c(0, 1), ylim = c(0, 1), cex = 1, cex.axis = 2, cex.lab = 2, ...)

Arguments

X	A matrix of genotype counts or frequencies with three columns (AA, AB, BB)
plottype	plottype=1 produces a plot of AB versus AA, plottype=2 produced a plot of BB versus AA.
xlab	A label for the x axis
ylab	A label for the y axis
asp	Aspec ratio (1 by default)
pch	Plotting charachter (19 by default)
xlim	Limits for the x axis (0-1 by default)
ylim	Limits for the y axis (0-1 by default)
cex	Character expansion factor (1 by default)
cex.axis	Character expansion factor for the axes (2 by default)
cex.lab	Character expansion factor for labels of axis (2 by default)
...	Additional arguments for the plot function

Value

NULL
