[jira] [Created] (SPARK-32073) Drop R < 3.5 support

Hyukjin Kwon created SPARK-32073:
------------------------------------

             Summary: Drop R < 3.5 support
                 Key: SPARK-32073
                 URL: https://issues.apache.org/jira/browse/SPARK-32073
             Project: Spark
          Issue Type: Improvement
          Components: R
    Affects Versions: 3.0.0
            Reporter: Hyukjin Kwon


Spark 3.0.0 is built by R 3.6.3 which does not support R < 3.5:

```
Error in readRDS(pfile) : cannot read workspace version 3 written by R 3.6.3; need R 3.5.0 or newer version.
```

In fact, with SPARK-31918, we will have to drop R < 3.5 entirely to support R 4.0.0.

This JIRA targets to drop R < 3.5 in SparkR.
