Arguments
Format
lu2004$x is a 30 x 403 matrix containing the log expression levels.
The rows contain the samples and the columns the genes.
lu2004$y is the age of for each sample.
Details
This data set contains measurements of the gene
expression of 403 genes from 30 human brain samples. In addition,
the age of each patient is provided.
