nsFilter {CLL} | R Documentation

## Nonspecific filtering boolean values for the sCLLex ExpressionSet object

### Description

nsFilter is the nonspecific filtering boolean values for the sCLLex ExpressionSet object. One filter was use: genes with an IQR greater than or equal to the median IQR (IQR performed on the rows of the expression matrix) have a TRUE value (passed the filter) and those that had an IQR less than the median have a FALSE value (did not pass the filter). We only filtered on variation.

### Usage

    data(nsFilter)

### Format

A named vector of logicals. The names are the Affymetrix identifiers and the values are booleans.

### Source

The CLL microarray data came from Dr. Sabina Chiaretti at Division of Hematology, Department of Cellular Biotechnologies and Hematology, University La Sapienza, Rome, Italy and Dr. Jerome Ritz at Department of Medicine, Brigham and Women's Hospital, Harvard Medical School, Boston, Massachusetts.
