data(terrycallow)
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.
Apo AI dataset is used by several authors to study cDNA microarray data normalization and significance analysis.
This data set is one part of Apo AI experiment by Callow et. al.(2000). Block one in the treatment group is chosen for this example. The whole Apo AI data set can be found from http://stat-www.berkeley.edu/users/terry/zarray/Html/apodata.html.
