Checks which cells (probes) are PMs and not

Description

Checks which cells (probes) are PMs and not.

Usage

## S3 method for class 'AffymetrixCdfFile'
isPm(this, units=NULL, force=FALSE, cache=TRUE, ..., verbose=FALSE)

Arguments

units	The units to be read. If NULL, all units are read.
...	Additional arguments passed to readCdfUnits.
force	If TRUE, cached results are ignored.
cache	If TRUE, results are cached.
verbose	A logical or Verbose.

Value

Returns a logical vector of length K, where K equals the total number of cells in the requested units. Note that the cells are ordered as they occur in the units, that is, not in incremental order.

Caching

This method caches a logical vector of length N, when N equals the number of cells on the array. The size of this vector is approximately 4*N bytes. The vector indicates if a cell is a PM or not.
