I am trying to read several .cel files from Affymetrix Exon Arrays with the R program. I have loaded the affy, affyio, oligo and pd.huex.1.0.st.v2 packages but when I write the command read.affybatch(dir()) it does not work and the following message appears:
AffyBatch object size of arrays=2560x2560 features (17 kb) cdf=HuEx-1_0-st-v2 (??? affyids) number of samples=1 Error in getCdfInfo(object) : Could not obtain CDF environment, problems encountered: Specified environment does not contain HuEx-1_0-st-v2 Library - package huex10stv2cdf not installed Bioconductor - huex10stv2cdf not available In addition: Warning messages: 1: In read.affybatch(dir()) : Incompatible phenoData object. Created a new one. 2: missing cdf environment! in show(AffyBatch)
I have looked for the huex10stv2cdf package through the internet but I cannot find it.
Moreover if I write read.celfile(dir()), a huge list appears without any information even when I ask for it.
Could anyone help me, please? Any advice would be really welcome.
