IlluminaHumanMethylationMSAmanifest

[zwang072005]

When I run the Minfi, I got error message cannot load annotation package IlluminaHumanMethylationMSAanno.20a1.hg38

please look at the following :
library(minfi)
library(IlluminaHumanMethylationMSAmanifest)
rawSet = read.metharray.exp(base=idatPath, targets=samp, force=TRUE, verbose=T)
rawSet@annotation <- c(array = "IlluminaHumanMethylationMSA", annotation = "20a1.hg38")
rawSet
