title: R expss - 'could not find function "setalloccol"'
body: <p>I'm trying to work through some of the examples in this article around table generations using expss - <a href="https://cran.r-project.org/web/packages/expss/vignettes/tables-with-labels.html" rel="nofollow noreferrer">https://cran.r-project.org/web/packages/expss/vignettes/tables-with-labels.html</a> - however, I am consistently getting the error <code>could not find function "setalloccol"</code> using the most basic crosstab functions of <code>cro</code> and <code>fre</code> with two variables:</p>
  
  <pre><code>&gt; cro(df$var1, df$var2)
  Error in setalloccol(ans) : could not find function "setalloccol"
  </code></pre>
  
  <p>I'm using R Studio 1.2.1335 and I've re-installed the packages dplyr, data.table, tidyr and expss itself, but I still seem to get this error with all these libraries running. I've googled the exact error I'm coming up with and there is absolutely zilch on this, so appreciate any help...</p>
