gplotMA: MA-plot: plot differences versus averages for Agilent...

Description Usage Arguments Details Value

Description

A generic function which produces an MA-plot for an object containing microarray data.

Usage

1
2
gplotMA(data, array = 1, columnProbe = "ControlType", probe = NULL,
  alpha = 0.5, size = 2)

Arguments

data

microarray data. Only for RGlist, MAlist or ELits class objects.

array

number array or name array to be displayed. Default 1.

columnProbe

column where contain probe number

probe

agilent type of probe. See in "ControlType" column. Default NULL, i.e. all.

alpha

transparent points (min = 1, max = 0). Default 0.25.

size

size of points. Default 2.

Details

An MA-plot is a plot of log-intensity ratios (M-values) versus log-intensity averages (A-values). If MA is an RGList or MAList then this function produces an ordinary within-array MA-plot. If MA is an MArrayLM object, then the plot is an fitted model MA-plot in which the estimated coefficient is on the y-axis and the average A-value is on the x-axis.

Value

A plot is created on the current graphics device.
