This function returns a data.frame of all the tagged variables stored in a
linelist. Note that the output is no longer a linelist, but a regular
data.frame.
Examples
if (require(outbreaks) && require(dplyr) && require(magrittr)) {
## create a tibble linelist
x <- measles_hagelloch_1861 %>%
tibble() %>%
make_linelist(
id = "case_ID",
date_onset = "date_of_prodrome",
age = "age",
gender = "gender"
)
x
## get a data.frame of all tagged variables
tags_df(x)
}
