Genomic Response to Brassinosteroid in Arabidopsis

Description

This data if from Affy ATH1 array experiments of genomic response to brassinosteroid in Arabidopsis conducted at two laoratories. The data set contains random selected 500 genes and 10 samples, 6 from lab 1 and 4 from lab 2. Data was pre-processed by RMA

Usage

data(arab)

Value

arab

matrix of gene expression levels of 500 genes from 10 samples, rows correspond to genes and columns to mRNA samples.

arab.cl

numeric vector indicating the treatment class, 5 brassinosteroid-treated cases (code 1) and 5 control cases (code 0)

arab.gnames

character vector containing the AffyID of the 500 genes for the expression matrix arab

arab.origin

numeric vector indicating the origin of the samples, 6 samples from lab 1 (code 1) and 4 samples from lab 2 (code 2)
