Description

This data set consists 4 variables.

Usage

data(terrycallow)

Format

A list with 3186 observations on 4 variables:
[ , 1] slide array number
[ , 2] id clone ID
[ , 3] ratio log_2frac{R}{G}
[ , 4] intensity 0.5log_2(RG)

where R is background adjusted signal intensity in the Cy5 channel, G is background adjusted signal intensity in the Cy3 channel.

Details

Apo AI dataset is used by several authors to study cDNA microarray data normalization and significance analysis.
