I 'm new to R! I 'm starting to work on my affymetrix data from GPL570 in R using affylmGUI.
when loading my data after loading Targets file, immediately I get these three errors :
1. Is GSM397626.CEL really a cell file ? tried reading as text, gzipped text, binary,gzipped binary, command console and gzipped command console formats.
2.error in assign ("Rawaffydata", rawaffydata, affylmGUIenvironment): object ''rawaffydata'' not found.
3.error in colnames(expres(rawaffydata)):
error in evaluating the argument 'x' in selecting a method for function 'colnames': error in expres(rawaffydata):
error in evaluating the argument 'object' in selecting a method for function 'expres': error:object 'rawaffydata' not found.
Thanks in advance.
