I combined two arrays using combinedArray() function from Minfi. I want to visualize the raw results using shinyMethyl however I run into an issue. i see someone posted something similar in 2017 ( and it was resolved so I'm confused - any help would be appreciated.

combined_array <- combineArrays(rgset_450,rgset_850,outType="IlluminaHumanMethylation450k") [convertArray] Casting as IlluminaHumanMethylation450k Loading required package: IlluminaHumanMethylation450kmanifest Loading required package: IlluminaHumanMethylationEPICmanifest
