Hi, I'm using R3.6 with the library affy in order to analyze data from 4 arrays from Affymetrix.

The problem is, when using the command "mas5(affy.data)", I get:

background correction: mas 
PM/MM correction : mas 
expression values: mas 
background correcting...Error in getCdfInfo(object) : 
  Could not obtain CDF environment, problems encountered:
Specified environment does not contain Clariom_S_Human
Library - package clariomshumancdf not installed
Bioconductor - clariomshumancdf not available

I looked around for a solution to the "Could not obtain CDF environment, problems encountered" error, but I couldn't find any meaningful answers.
