mammary: Microarray gene expression time course data for mammary gland development in mice

Description

The data contains 30 genes identified using cluster analysis from 12488 probe sets representing approximately 8600 genes. The data are measured over 54 arrays of 3 replicates each on 18 time points of the developmental stages of mammary gland in mice. See Stein et al. (2004) for more details.

Usage

Format

Data is in longitudinal format with 30 columns, 54 rows and a number of extra attributes (see R package longitudinal).

Source

This data is described in Stein et al. (2004) and can be freely obtained from the R package smida.
