SeSAMe-Minfi interaction

SeSAMe can be converted back and forth from Minfi RGChannelSet in multiple ways. One can sesamize a minfi RGChannelSet which returns a GenomicRatioSet. Here we are illustrating using the FlowSorted.Blood.450k object, which is distributed in the minfi::RGChannelSet.

library(sesame)
library(FlowSorted.Blood.450k)

grSet <- sesamize(FlowSorted.Blood.450k[,1:4])
