Hello,
I've done an Illumina 850k analysis and I received just the .idat files and a .rds file with bvalues already normalized. I would like to highlight the reference info and I've download the EPICannotation. Unfortunately, the amount of CGs recorded in the .rds file is higher than the one in the Illumina annotation. Is there some function that can read the CGs info in both the dataframes and return a matrix with just the ones in common between the two?
