[jira] [Created] (ARROW-17533) [R] Implement asof join

Jonathan Keane created ARROW-17533:
--------------------------------------

             Summary: [R] Implement asof join
                 Key: ARROW-17533
                 URL: https://issues.apache.org/jira/browse/ARROW-17533
             Project: Apache Arrow
          Issue Type: New Feature
          Components: R
            Reporter: Jonathan Keane


With ARROW-16083 we have asof joins, could we expose this in R?

Docs for the node: https://arrow.apache.org/docs/cpp/api/compute.html?highlight=asof#_CPPv4N5arrow7compute19AsofJoinNodeOptionsE

A possible syntax might be (there does not appear to be a syntax in dplyr for this already): 

{code}
asof_join(table1, table2, by = "field", tolerance = 1) 
{code}
