In xps: Processing and Analysis of Affymetrix Oligonucleotide Arrays including Exon Arrays, Whole Genome Arrays and Plate Arrays

Description Usage Arguments Details Value Note Author(s) See Also Examples

Create class SchemeTreeSet accessing ROOT scheme file.

1	root.scheme(rootfile = character(0), add.mask = FALSE)

`rootfile`	name of ROOT scheme file, including full path.
`add.mask`	if `TRUE` mask information will be included as slot `mask`.

An S4 class SchemeTreeSet will be created, serving as R wrapper to the ROOT scheme file rootfile.

A SchemeTreeSet object.

Use this function to access the ROOT scheme file from new R sessions to avoid creating a new ROOT scheme file for every R session.

Do not set add.mask=TRUE for exon arrays unless you know that your computer has sufficient RAM.
