I updated R and Bioconductor to use the new ChAMP package for EPIC arrays. In contrast to what is written in the manual, it seems that probe.features.epic does not exist, and that probe.features entails now the EPIC data and not the 450K data. How is this possible?
> dim(probe.features)  867531 2 > dim(probe.features.epic) Error: object 'probe.features.epic' not found
In addition, the probe.features data entails only the columns CHR and MAPINFO and not all the other columns (gene, feature,..) it should have.
> head(probe.features) CHR MAPINFO cg07881041 19 5236016 cg18478105 20 61847650 cg23229610 1 6841125 cg03513874 2 198303466 cg09835024 X 24072640 cg05451842 14 93581139
Does anyone know how to solve this?
