Hi,

I was trying to read in a file test.txt, which has the following data:
 norm	norm	norm	class	class	class
a	1	2	3	4	5	6
b	3	4	5	6	7	8
c	5	6	7	8	9	10


in my R code, I do the following:
---------------------------------------------------
> mat <- read.table('test.txt',header=T,row.names=1,sep='\t')
> mat

  norm norm.1 norm.2 class class.1 class.2
a    1      2      3     4       5       6
b    3      4      5     6       7       8
c    5      6      7     8       9      10
> 
--------------------------------------------------
What do I need to do so that I don't get 'norm.1', 'norm.2' etc., but just 'norm', 'norm'..,i.e. without the numbers.
thanks,
