roxygen2 importFrom and binary operator

问题

What is the way to format a call to importFrom while using roxygen2?

I can see two approaches:

importFrom base %in%

or

importFrom base `%in%`

Obviously we wouldn't import a base function into a package but this is for demo's sake.

回答1:

I tested it out HERE and it seems:

importFrom base %in%

is appropriate
