Ian Cook created ARROW-12291: -------------------------------- Summary: [R] Determine the type of an unevaluated expression Key: ARROW-12291 URL: https://issues.apache.org/jira/browse/ARROW-12291 Project: Apache Arrow Issue Type: Improvement Components: R Reporter: Ian Cook
There would be several benefits to knowing the data type of an expression before its value has actually been computed. Probably the greatest benefit would be that other expressions could then behave dynamically based on the data types of their inputs. Consider how this capability might be implemented. -- This message was sent by Atlassian Jira (v8.3.4#803005)
