i Is your data `sda`-like?
Caused by error in `abort_if_missing_names()`:
! `data` must have all the expected names.
x Missing names: emission_factor_metric, emission_factor_value.

x `zero_row` has zero rows.

with too many sectors errors gracefully

`data` must have a single value of `sector`.

throws expected warning about API change

The `data` argument of `plot_emission_intensity()` must be prepped already as of r2dii.plot 0.4.0.
i From the next release you will need to call `r2dii.plot::plot_emission_intensity(data)` prior to calling `r2dii.plot::plot_emission_intensity()`.
i Alternatively custom data preparation will also become possible.
