R help - May 2011 - How to get rid of the index in result file

Hi,

I am running some function in Ubuntu command line and get some problem. I used
some command like below

$ R --slave -vanilla < my_infile > my_outfile

The return should be one number in the my_outfile. In the my_infile, I call one
extra function and it has code like "return x".

However, in the output file my_outfile

It shows

[1] 2.35343

How do I get only

2.35343

I mean to get rid of "[1]" part. Thanks a lot!

Hi Yighua,

Try
> m <- 2.35343
> m
[1] 2.35343
> cat(m)
2.35343

HTH,
Jorge
