Usage

fill_dates(df, grouping_vars, date_var)

Arguments

df	the data.frame to fill in
grouping_vars	a character vector with the variable names that define the grouping structure that will uniquely identify the relavant units of observation
date_var

Examples

set.seed(123)
tmp <- tibble(County = sample(LETTERS[1:3], 15, replace = TRUE),
              Date = sample(seq(as.Date("2020-07-01"), as.Date("2020-07-07"), by = 1),
                            15, replace = TRUE)) %>%
  distinct(.) %>%
  arrange(County, Date)
