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 |
Non-numeric columns will be dropped with a warning.
A data frame
data <- expand.ev(amt = c(100,200,300)) expand_observations(data, times = seq(0,48,2))
