Insert observations into a data set
expand_observations(data, times, unique = FALSE, obs_pos = -1L)
| data | a data set or event object |
|---|---|
| times | a vector of observation times |
| unique | `logical`; if `TRUE` then values for `time` are dropped if they are found anywhere in `data` |
| obs_pos | 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
Non-numeric columns will be dropped with a warning.
