The matrix contains the Beta values of a set of 36 samples from the Illumina Infinium HumanMethylation 450k array
data(betaMatrix)data(betaMatrix)
A data frame with 485577 observations (rows) and 36 samples (columns)
Column names correspond to the sample names (of the form 5621146025_R06C02)
normalizeARRm for normalization of the Beta values,
greenControlMatrix and redControlMatrix for the associated negative control probe data.
data(betaMatrix)data(betaMatrix)
The matrix contains the raw intensities of 600 negative control probes measured in the green channel for 36 samples from the Illumina Infinium HumanMethylation 450k array
data(greenControlMatrix)data(greenControlMatrix)
A data frame with 600 observations (rows) and 36 samples (columns)
Column names correspond to the sample names (of the form 5621146023_R01C01). These samples correspond to those of betaMatrix.
getBackground to obtain background information,
redControlMatrix for the equivalent negative contol probes in the red channel
