[R] Reading in a tab delimitated file

[amindlessbrain]

Hi all,

I have a total newbie question, but I could really use some help. 

I need to read in this file:

SampleID	Disease
E-CBIL-28-raw-cel-1435145228.cel	1
E-CBIL-28-raw-cel-1435145451.cel	2	
E-CBIL-28-raw-cel-1435145479.cel	2	
E-CBIL-28-raw-cel-1435145132.cel	3		
E-CBIL-28-raw-cel-1435145417.cel	3		
E-CBIL-28-raw-cel-1435145301.cel	2	
E-CBIL-28-raw-cel-1435145558.cel	1
E-CBIL-28-raw-cel-1435145073.cel	3		
E-CBIL-28-raw-cel-1435145196.cel	2	
E-CBIL-28-raw-cel-1435145511.cel	1	
E-CBIL-28-raw-cel-1435145336.cel	3	
E-CBIL-28-raw-cel-1435145260.cel	2	
E-CBIL-28-raw-cel-1435145167.cel	2	
E-CBIL-28-raw-cel-1435145387.cel	3			
E-CBIL-28-raw-cel-1435145099.cel	3	

(I'm not sure why the disease column isn't showing up as a tab here, but it
is sep by "\t" in my file. 

I've tried several variations on these:

pd <- read.AnnotatedDataFrame ("new_treat.txt" , header = TRUE ,  sep="\t",
row.names = "SampleID", colClasses = c(Disease = "character"))

And I keep on getting this error:

Error in read.table(filename, sep = sep, header = header, quote = quote,  : 
  more columns than column names

Any help would be very very very appreciated!

Thanks!
