Neal Richardson commented on ARROW-5977:
----------------------------------------
Right, that was the other option that I said that all of the R readers support.
We could support both ways, but the benefits of a separate vector of column
names argument would be (1) you don't have to specify types for all other
columns; (2) you wouldn't have to know the names of the other columns; and (3)
you can't specify desired column order in the column_types because it is a map.
