frma (version 1.24.0)

GNUSE: GNUSE

Description

Computes the generalized normalized unscaled standard error (a measure of microarray quality).

Usage

GNUSE(object, medianSE=NULL, type=c("plot", "values", "stats", "density"), ...)

Arguments

object

an ExpressionSet or frmaExpressionSet containing standard errors produced by frma

medianSE

median standard errors to be used. If NULL, these are obtained from the correct frmavecs package.

type

the desired output

...

additional graphical parameters for types plot or density

Value

If type is plot, boxplots of GNUSE values are displayed. If type is values, the GNUSE values are returned. If type is stats, the median, IQR, 95th, and 99th percentiles are reported. If type is density, a density plots of GNUSE values are displayed.

Examples

  library(frma)
  library(frmaExampleData)
  data(AffyBatchExample)
  object <- frma(AffyBatchExample)
  GNUSE(object, type="stats")
