Examples

set.seed(999)
dat <- as.Date(Sys.Date()) + sample(-3:50, 100, replace = TRUE)
x <- incidence(dat, interval = "month")
get_dates(x)
#> [1] "2020-07-01" "2020-08-01" "2020-09-01"
get_dates(x, position = "middle")
#> [1] "2020-07-16" "2020-08-16" "2020-09-16"
set.seed(999)
dat <- as.Date(Sys.Date()) + sample(-3:50, 100, replace = TRUE)
x <- incidence(dat, interval = "month")
get_dates(x)
#> [1] "2020-07-01" "2020-08-01" "2020-09-01"
get_dates(x, "center")
#> [1] "2020-07-16" "2020-08-16" "2020-09-16"
get_dates(x, "right")
#> [1] "2020-08-01" "2020-09-01" "2020-10-01"

# Return dates by number of days from the first date
get_dates(x, count_days = TRUE)
#> [1]  0 31 62
get_dates(incidence(-5:5), count_days = TRUE)
#>  [1]  0  1  2  3  4  5  6  7  8  9 10
