Hi everyone, My purpose is to read a .CEL file into R. The .CEL file was created from a .CAB by using DTT software found on Affymetrix website I read the .CEL file in R using ReadAffy as follows: > d2=ReadAffy(widget=T) and I complete the fields as required. It does not complain. For example I could find the description: > description(d2) Experimenter name: BB Laboratory: FFL Contact information: Title: Heter URL: www.bioconductor.org A 1 word abstract is available. Use 'abstract' method. Information is available on: samples, preprocessing But if I want to see the values for MM I get an error: > mm(d2)[1:2] Note: You did not specify a download type. Using a default value of: Win32 This will be fine for almost all users Error in if ((is.null(deps)) || (length(deps) == 0) || (deps == "")) return(NULL) : missing value where TRUE/FALSE needed I appreciate any ideas you may have. Thank you. Melania Rm 15-433, ext 4886 Fax: (416) 946-2048
