ma_plot: MA plot

In ssarda/genomeutils: Utilities for Genome Analysis

Description

Takes two vectors x and y and plots M=y-x versus A=(x+y)/2. A smooth curve is added to show trends.

Usage

ma_plot(x, y, n = 10000, subset = NULL, xlab = NULL, ylab = NULL,
  curve.add = TRUE, curve.col = 2, curve.span = 1/2, curve.lwd = 2,
  curve.n = 2000, ...)

Arguments

x	a numeric vector
y	a numeric vector
n	a numeric value to subsample data
subset	index of the points to be plotted
xlab	a title for the x axis
ylab	a title for the y axis
curve.add	if TRUE a smooth curve is fit to the data and displayed. The function loess is used to fit the curve.
curve.col	a numeric value that determines the color of the smooth curve
curve.span	is passed on to loess
curve.lwd	the line width for the smooth curve
curve.n	a numeric value that determines the sample size used to fit the curve. This makes fitting the curve faster with large datasets
...	further arguments passed to plot
