Hello, I would be grateful for any help or advise on the following issue. I have affy files in different directories and want to point ReadAffy() to read files from all directories. Is there a way I can do this via setwd but in a loop and if so how? For example can I say : setwd("C:\\RawArrayData\\Cel Files\\U133\\*") X <- ReadAffy() Also similarly, I wrote a function that annotate files in separate directories. Can I run that on the root and get it to annotate all files below the root directory in windows i.e. the children of the root directory. Many Thanks, _________________________________________________________________ Imagine a life without walls.? See the possibilities.

Hi. How about an alternative. Something like: fn <- dir(".","CEL",recursive=TRUE) (e.g. replace "." with your directory "C:\\RawArrayData ...") x <- ReadAffy(filenames=fn) Cheers, Mark On 09/12/2008, at 6:07 AM, Ruppert Valentino wrote: > > Hello, > I would be grateful for any help or advise on the > following issue. > > I have affy files in different directories and want to point > ReadAffy() to read files from all directories. > Is there a way I can do this via setwd but in a loop and if so how? > > For example can I say : > > setwd("C:\\RawArrayData\\Cel Files\\U133\\*") > X <- ReadAffy() > > > Also similarly, I wrote a function that annotate files in separate > directories.
