Mice Dataset

Description

This is the Mice dataset used in Chun and Keles (2010).

Usage

 data(mice) 

Format

A list with two components:

x

Marker map data. A matrix with 60 rows and 145 columns.

y

Gene expression data. A matrix with 60 rows and 83 columns.

Details

The Mice dataset was published by Lan et al. (2006). Matrix x is the marker map consisting of 145 microsatellite markers from 19 non-sex mouse chromosomes. Matrix y is gene expression measurements of the 83 transcripts from liver tissues of 60 mice. This group of the 83 transcripts is one of the clusters analyzed by Chun and Keles (2010). See Chun and Keles (2010) for more details.
