Insert observations into a data set
expand_observations(data, times, unique = FALSE, obs_pos = -1L)a data set or event object
a vector of observation times
`logical`; if `TRUE` then values for `time` are dropped if they are found anywhere in `data`
determines sorting order for observations; use `-1` (default) to put observations first; otherwise, use large integer to ensure observations are placed after doses
A data frame with additional rows for added observation records.
Non-numeric columns will be dropped with a warning.
