I am trying to analyze HTA platform. I am able to use Affy CDF. I am trying to use Brainarray CDF. I could install packages hta20hsentrezgcdf, hta20hsentrezgprobe, hta20hsentrezg.db in R. I am trying to use function read.celfiles but it is throwing me the error.
affyGeneFS <- read.celfiles(geneCELs, pkgname = "hta20hsentrezgcdf")
The error is
Error in (function (classes, fdef, mtable) :
unable to find an inherited method for function ‘kind’ for signature ‘"environment"’.
I even tried
affyGeneFS <- read.celfiles(geneCELs, cdfname=cdf). It threw me the following error.
Error: These do not exist:
I believe readAffy function uses cdfname argument. I am not sure how to use the brainarray cdf in oligo package.
