SD: SD Assessment Functions
In affycomp: Graphics Toolbox for Assessment of Affymetrix Expression Measures

Description Usage Arguments Details Value Author(s) Examples

These functions create assessments, figures, and tables for expression standard errors

affycomp.figure7(l,main="Figure 7")
affycomp.compfig7(l,method.names=as.character(1:length(l)),
                  main="Figure 7")
tableSD(l,method.names=NULL)

`l`	a list of lists with the necessary components to create the Figure. See details.
`method.names`	a character vector with the names of the expression measures methodologies being compared.
`main`	title of the Figure.

This uses the dilution data. The exprsets need to have standard error estimates in the assayDataElement(exprset,"se.exprs"). Read the vignette for more details. The functions work similarly to those assessing expression measures.

All these files need the result of assessSD

Depends on the call.
