Hi I'm having difficulty accessing data that I have placed into R using marrayInput After creating a "raw" file using marrayRaw and appropriate layout, gnames and target files I wasn't sure how to access this data for marrayNorm. When I look at the files I've loaded in there is no 00Index file I've created files with .Rdata suffix and if I look at the file it appears to have saved all the binary data correctly I would like to set up new project directory work space similar to the data(swirl) set up If someone could advise how to do this Thanks Jason
