Hi

I tried the following steps:

biocLite("hgu133plus2cdf")

library(affy)
library(simpleaffy)
library(affyQCReport)
setwd("/temp/Cel-Data")
celData <- ReadAffy()
sampleNames(celData)
hist(celData)

I get the following error when I try hist(celData):

Error in getCdfInfo(object) :
  Could not obtain CDF environment, problems encountered:
Specified environment does not contain HuGene-1_0-st-v1
Library - package hugene10stv1cdf not installed
Bioconductor - hugene10stv1cdf not available

I looked up for the missing package i.e. hugene10stv1cdf at
http://www.bioconductor.org/packages/release/data/annotation/ and the
closest I could find was
http://www.bioconductor.org/packages/release/data/annotation/html/hugene10stv1.r3cdf.html,
which I installed. But I still get the error.

I am new to R so I might have done some thing naive. Please let me know
where I have gone wrong.

Thanks for your time.
