HWGenotypePlot

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
