Should we support term in R formula is type vector? I think it's illegal in R.

I think it makes sense when using RFormula in a ML pipeline (not necessarily in R).

…ures Currently `summary()` fails on a GLM model fitted over a vector feature missing ML attrs, since the output feature attrs will also have no name. We can avoid this situation by forcing `VectorAssembler` to make up suitable names when inputs are missing names. cc mengxr Author: Eric Liang <ekl@databricks.com> Closes #10323 from ericl/spark-12346. (cherry picked from commit 5e492e9) Signed-off-by: Xiangrui Meng <meng@databricks.com>
