And how to read a file with a BOM is actually discussed in detail in
the 'R Data Import/Export' manual of 2.12.2 RC.
What should be ASCII files with BOMs seem to be cropping up rather
frequently these days: the recent culprits are Mac applications with
origins on Windows (SPSS was one, some version of Excel another).

Thanks for all the people that replied my message. The text file indeed has
"\uFEFF". I have fixed the text file by using 'gvim -b'.

What you describe could be a bug (in which case providing your OS and R
version info per the posting guidelines would be a minimum requirement to
get it fixed) or a control character that is actually in your file (which
you might need a binary editor to see).

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
