affySpikeIn
(Package: ROTS) :
Gene expression data from the Affymetrix spike-in experiment
The Affymetrix HG-U95Av2 spike-in data contains two groups of 12 samples. In this carefully controlled experiment, it is known that 14 genes are differentially expressed between the two sample groups, while the rest of the genes are equally expressed. In order to reduce the running time of the vignette example, this package uses a subset of 1000 genes of the original dataset including all the spiked genes with 5 samples from each group. The preprocessed RMA-normalized data were obtained from the Bioconductor 2.2 package DEDS. For more details about the spike-in experiment, see http://www.affymetrix.com.
upsSpikeIn
(Package: ROTS) :
Protein expression data from the CPTAC Technology Assessment (Study 6)
The data contains preprocessed expression values from CPTAC Technology Assessment, where equimolar concentrations of 48 human proteins (Sigma UPS 1) are spiked in five different concentrations into yeast proteome background and then processed. The example data contains only two groups from the study 6.
