enw_add_latest_obs_to_nowcast: Add latest observations to nowcast output

In seabbs/epinowcast: Flexible Hierarchical Nowcasting

Add latest observations to nowcast output

Description

Add the latest observations to the nowcast output. This is useful for plotting the nowcast against the latest observations.

Usage

enw_add_latest_obs_to_nowcast(nowcast, obs)

Arguments

nowcast	A data.frame of nowcast output from enw_nowcast_summary().
obs	An observation data.frame containing reference_date columns of the same length as the number of rows in the posterior and the most up to date observation for each date. This is used to align the posterior with the observations. The easiest source of this data is the output of latest output of enw_preprocess_data() or enw_latest_data().

Value

A data.frame of nowcast output with the latest observations added.
