sorlie: Gene expression data for breast cancer tumors
Description
Gene expression levels of 456 genes for 85 tissue samples.
The original data had missing values scattered throughout the matrix.
10-nearest neighbours was used for imputation, as described in Chipman,
Hastie and Tibshirani (2003).
Usage

Arguments
Format
A matrix with 456 rows and 85 columns.
