Relative M vs. A plots

Description

Create boxplots of M or M vs A plots. Where M is determined relative to a specified chip or to a pseudo-median reference chip.

Usage

MAplot(object,...)
Mbox(object,...)
ma.plot(A, M, subset = sample(1:length(M), min(c(10000, length(M)))),
show.statistics=TRUE, span=2/3, family.loess="gaussian", cex = 2,plot.method=c("normal","smoothScatter"),...)

Arguments

object An AffyBatch-class
... Additional parameters for the routine
A A vector to plot along the horizonal axis
M A vector to plot along vertical axis
subset A set of indices to use when drawing the loess curve
show.statistics If true some summary statistics of the M values are drawn
span span to be used for loess fit.
family.loess "guassian" or "symmetric" as in loess.
cex Size of text when writing summary statistics on plot
plot.method a string specifying how the plot is to be drawn.
