mvaPair2: plot MA for each pair of columns

In ABarray: Microarray QA and statistical data analysis for Applied Biosystems Genome Survey Microrarray (AB1700) gene expression data.

Description

MA plot for each pair of columns

Usage

mvaPair2(x, y = NULL, snThresh = 3, labels = colnames(x), log.it = FALSE, span = 2/3, 
    family.loess = "gaussian", digits = 3, line.col = 2, main = "MA plot", ... )

Arguments

x	expression matrix
y	S/N ratio matrix
snThresh	S/N threshold
labels	name for the labels
log.it	should data be log transformed
span	span of the plot
family.loess	curve fitting
digits	number of digits to display
line.col	size of the line col
main	title for the MA plot
...	additional argument

Details

If S/N ratio is available, probes with S/N < 3 in both array will be colored differently.

Value

MA plot
