maplot: A Function to make MA plots from all arrays.
Description
This function creates an MA plot for all arrays in either an ExpressionSet
or a matrix. A 'baseline' array is created using the median expression for
each gene, and each array is then compared to the baseline array.
Usage
maplot(object, layout = NULL, ...)
Arguments
object
An ExpressionSet or matrix containing log-transformed array
data.
layout
A numeric vector, length two. Best results will be obtained if
both values are the same, and between 2 and 5 (e.g., c(3,3))
...
Other arguments that will be passed down to the xyplot
function from the lattice package.
Value
No output. Used only for the side effect of creating MA plots.
