## Experimental design potato abiotic stress

### Description

`edesign.abiotic` contains experimental set up of a time course microarray experiment where potato plants were submitted to 3 different abiotic stresses.

### Usage

    data(edesign.abiotic)

### Format

A matrix with 36 rows and 6 columns

rows [1:36] "Control 3h 1" "Control 3h 2" "Control 3h 3" "Control 9h 1" ...

columns [1:6] "Time" "Replicates" "Control" "Cold" "Heat" "Salt"

### Details

Arrays are given in rows and experiment descriptors are given in columns. Row names contain array names.

`"Time"` indicates the values that variable Time takes in each hybridization.

`"Replicates"` is an index indicating replicate hyridizations, i.e. hybridizations are numbered, giving replicates the same number.

`"Control"`, `"Cold"`, `"Heat"` and `"Salt"` columns indicate array assigment to experimental groups, coding with 1 and 0 whether each array belongs to that group or not.
