datamash: "antimode" returns lowest, instead of least common, value

[Kingsley G. Morse Jr.]

Package: datamash
Version: 1.8-1
Severity: normal

Dear Maintainer,

Thanks for maintaining datamash.

I like that it lets shell scripts calculate
statistics.

The main reason I'm writing is datamash's
"antimode" statistical grouping operation did not
work as I expected.

datamash's man page says its "antimode"
statistical grouping operation is for the "least
common value".

But, my testing suggests datamash's "antimode"
instead returns the lowest value.

My simple test is to 

1.) copy 

        echo -e "1\n1\n2" | datamash antimode 1

    to the bash command prompt and 

2.) press the <enter> key.


At least on my computer, it returns "1".

But, I expected it to return "2", because "2" is
the least common value.

I suppose maybe either datamash's man page and/or code
could be changed so they're consistent.

Thanks again for datamash!

Kind regards,
Kingsley
