As far as I can see, the failing build is due to #220, and nothing to do with updates in this PR.

The error is "Running examples in 'tlf-Ex.R' failed". Where does tlf-Ex.R come from? I cannot find this file at all

* checking examples ... ERROR
Running examples in 'tlf-Ex.R' failed
The error most likely occurred in:

The xxx-Ex.R are generated on build from examples... Meaning some of the examples are failing.
