how to read MoGene-2_0-st.CEL files

Hi I am running script to read the MoGene-2_0-st.CEL file but unfortunately the error is coming

"Error in ReadAffy() : could not find function "ReadAffy".

Can any one please help how i can read :CEL file and perform rma.

#########CONSTRUCTING ESETs WITH .CEL FILES THROUGH AFFY###############
source("http://bioconductor.org/biocLite.R")
biocLite("affy")#Installs Affy i
library(affy)#Deploys Affy Package

setwd("C:/Users/akp0396//RTest cell file/Helene CEL file")#Define in folder 
data<-ReadAffy()#Automatically reads the .CEL files present in the folder
data<-rma(data)

Error in ReadAffy() : could not find function "ReadAffy"

B-also I have tried by deploying "oligo" but then also i am getting error message which is as 
 oligo:::getCelChipType("C:/Users/akp0396//RTest cell file/Helene CEL file", TRUE)

Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) : 
  namespace ‘BiocGenerics’ 0.26.0 is already loaded, but >= 0.27.1 is required

Which R version are you using?; What happened after you ran library(affy)? Also note the error on BiocGenerics

I am using R version 3.5.1 (2018-07-02) -- "Feather Spray". BiocGenerics is loaded with affy:

require(affy)
Carregando pacotes exigidos: affy
Carregando pacotes exigidos: BiocGenerics
Carregando pacotes exigidos: parallel

Hi Kevin, I am a new user and I am learning so expect experts like you may handle with experience :) while ran the library(affy) I am getting the Error ReadAffy() : could not find function "ReadAffy" I am still searching appropriate scripts to read and perform rma.

Thanks for your support

Yes! but unfortunately after performing that, the problem didn't solve . so I removed 'oligo' and I reinstall library(oligo) with packages("Rcpp") then after that I can able read and perform the RMA.

Thanks for all the information and support :)

Best Regards Aviseka
