Neal Richardson commented on ARROW-18062:
-----------------------------------------
The slice PR added a UDF registration in .onLoad:
https://github.com/apache/arrow/compare/02c671a3791d5f92d3ad0260396e2ee9c286670f...dd9c2243421e165686aaff5e3ff7267ae30e2e14#diff-d33e59c0468a492a62bbb832ed1b4a925e201bbe20cd22b36f24c2483f8bc738R165
Are UDFs known not to work on R < 4.0?

> It is currently erroring for R 3.5 and 3.6 in the nightlies with this error.
> The line of code where the error comes from was added in ARROW-16444 but
