| <h2 id="function-mappings">Function mappings<a class="anchor" aria-label="anchor" href="#function-mappings"></a></h2> |
| <p>In the list below, any differences in behavior or support between Acero and |
| the R function are listed. If no notes follow the function name, then you |
| can assume that the function works in Acero just as it does in R.</p> |
| <p>Functions can be called either as <code>pkg::fun()</code> or just <code>fun()</code>, i.e. both |
| <code>str_sub()</code> and <code><a href="https://stringr.tidyverse.org/reference/str_sub.html" class="external-link">stringr::str_sub()</a></code> work.</p> |
| <p>In addition to these functions, you can call any of Arrow's 246 compute |
| functions directly. Arrow has many functions that don't map to an existing R |
| function. In other cases where there is an R function mapping, you can still |
| call the Arrow function directly if you don't want the adaptations that the R |
| mapping has that make Acero behave like R. These functions are listed in the |
| <a href="https://arrow.apache.org/docs/cpp/compute.html" class="external-link">C++ documentation</a>, and |
| in the function registry in R, they are named with an <code>arrow_</code> prefix, such |
| as <code>arrow_ascii_is_decimal</code>.</p><div class="section"> |
