Add probe color channel and basic annotation information based on the annotation library of Illumina methylation microarray
}
\usage{
addAnnotationInfo(methyLumiM, lib = NULL, annotationColumn=c('COLOR_CHANNEL', 'CHROMOSOME', 'POSITION'))
}
%- maybe also 'usage' for other objects documented here.
\arguments{
  \item{methyLumiM}{a MethyLumiM object includes Illumina Infinium methylation data}
  \item{lib}{Annotation library of Illumina methylation microarray. For example, "IlluminaHumanMethylation27k.db" for 27k array, "IlluminaHumanMethylation450k.db" for 450k infinium array }
  \item{annotationColumn}{only include 'COLOR_CHANNEL', 'CHROMOSOME' and 'POSITION' information}
}
\value{
return the MethyLumiM object with COLOR_CHANNEL, CHROMOSOME and chromome POSITION information added to the featureData.
