title: Using Roxygen2 for my utility functions
body: <p>In my analysis projects (not a package), I usually have utility functions that I <code>source()</code> in different analysis scripts.</p>
  
  <p>I've been using the Roxygen2 documentation convention (e.g. starting the documentation with <code>#'</code>, which is well supported in RStudio.</p>
  
  <p>Can I make these documentation available via <code>help(my_utility_function)</code>? Everything I read so far uses <code>Roxygen2</code> and <code>devtools::document()</code> in the context of a package. Indeed, when I tried to use <code>devtools::document()</code>, it complains about not being able to find the package root.</p>
