Intensities: Regular and Negative probes from one Illumina microarray

Description

Provides probe intensities measured on Illumina Human HT-6 v4 Expression BeadChip, from one control in the NOWAC cohort (for more details, see Plancade S., Rozenholc Y. and Lund E. BMC Bioinfo 2012). Vectors Regular and Negative contain the intensities of regular and negative probes, respectively.

Usage

data(RegNegIntensities_Example)

Format

A list Intensities with two elements: a vector Regular of length 25 519 and a vector Negative of length 759.
