Mis-coded values field is not being detected

[kylebaron]

Summary

As a user, I want yspec to detect when I have mis-coded values as a list of lists.

Tests

• tests/testthat/test-load_spec.R
  • Error when values is mis-coded as list of lists

Example

EVID: 
  values: [a: 1, b: 2]

> spec <- ys_load("inst/spec/test/values-list-of-lists.yml")
 Error: invalid column data
In file: values-list-of-lists.yml
column: EVID
- values field includes non-atomic data
