Description

In the docs for schema(), the ellipses argument is documented as "named list of data types".

However, if I create a schema using a named list, e.g.

 

share_schema <- schema(
  list(
    company = utf8(),
    price = float64(),
    date = date32()
  )
)

I get the error: {{Error: !is.null(nms <- names(.list)) is not TRUE }}

We should:

1. Rephrase the documentation of that argument so it doesn't say to use a named list
2. Update the error message shown if a named list is supplied to be a little clearer about what the user has done wrong
