title: Is there an R function for cell-based functions across multiple tables?
body: <p>I'm trying to find an R function that will allow me to take a cell-wise sum (or any anonymous function) across an arbitrary number of dataframes (which could be grouped together in a list).</p>
  <p>One way to think of this could be that there is colsum, rowsum, but no cellsum.</p>
  <p>purrr::pmap doesn't seem to help with this, since it doesn't allow for anonymous functions with an arbitrary number of arguments.</p>
