Better way to display indicator function.

I have an indicator function I am displaying in an R manual. I am trying to make it as one line (and more readable) so it looks good in the HTML version of the R documentation.

I'm looking to make the current function more streamlined. Dason did this for me previously using max, but I don't think I can make that work in this case.

So here was what Dason did before...

How can I streamline this indicator function (maybe it already is but I thought I'd throw this out in case there's a better way):

Well then that quantity can only take on a value of either 0 or 1 - you don't need the indicator at all. \((\sum x_i^N) mod 2\) gives you the same exact thing as what you have.

Gotcha Dason. In R coding my thought was this (x %% 2 > 0) evaluates to logical TRUE/FALSE. Hence why I thought the need to convert to 1/0. So you're saying no need to convert. Is this correct?
