Hi,

I have the following input file.
$ cat main.txt
CEL_A CELL_B
1 4
2 5
2 6

Then I run read.table in R.

> f=read.table('main.txt', header=T, check.names=F, sep='\t')
> head(f)
  \ufeffCEL_A CELL_B
1    1      4
2    2      5
3    2      6
> f$CEL_A
NULL

I'm not sure where the special character \ufeff comes from. Could anybody
let me know what is the problem?

Thanks,
John
