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.
