This function lists the names of all available Arrow C++ library compute functions.
These can be called by passing to call_function(), or they can be
called by name with an arrow_ prefix inside a dplyr verb.
list_compute_functions(pattern = NULL, ...)Optional regular expression to filter the function list
Additional parameters passed to grep()
A character vector of available Arrow C++ function names
The resulting list describes the capabilities of your arrow build.
Some functions, such as string and regular expression functions,
require optional build-time C++ dependencies. If your arrow package
was not compiled with those features enabled, those functions will
not appear in this list.
Some functions take options that need to be passed when calling them
(in a list called options). These options require custom handling
in C++; many functions already have that handling set up but not all do.
If you encounter one that needs special handling for options, please
report an issue.
Note that this list does not enumerate all of the R bindings for these functions.
The package includes Arrow methods for many base R functions that can
be called directly on Arrow objects, as well as some tidyverse-flavored versions
available inside dplyr verbs.
