Extracts an in-memory ExpressionSet object

Description

Extracts an in-memory ExpressionSet object from a ChipEffectSet object. Note that any modifications done to the extracted object will not be reflected in the original chip-effect set.

Usage

## S3 method for class 'ChipEffectSet'
extractExpressionSet(this, ..., logBase=2, orderUnitsBy=c("asis", "lexicographic"),
  annotationPkg=NULL, verbose=FALSE)

Arguments

...	Optional argument passed to *extractMatrix().
logBase	An integer specifying the base to use when log-transforming the signals. If NULL, the signals are not transformed, but kept as is.
annotationPkg	(optional) A character string specifies a Bioconductor (ChipDb, CDF environment or PDInfo) annotation package, which then sets the 'annotation' slot of the returned object. If "ChipDb", "cdf" or "PDInfo" th corresponding ChipDB, CDF environment or PDInfo package is inferred from the CDF's chip type.
verbose	See Verbose.

Value
