Examples

set.seed(999) dat <- as.Date(Sys.Date()) + sample(-3:50, 100, replace = TRUE) x <- incidence(dat, interval = "month") get_dates(x)
#> [1] "2019-03-01" "2019-04-01" "2019-05-01"
get_dates(x, position = "middle")
#> [1] "2019-03-16" "2019-04-16" "2019-05-16"
set.seed(999) dat <- as.Date(Sys.Date()) + sample(-3:50, 100, replace = TRUE) x <- incidence(dat, interval = "month") get_dates(x)
#> [1] "2019-03-01" "2019-04-01" "2019-05-01"
get_dates(x, "center")
#> [1] "2019-03-16" "2019-04-16" "2019-05-16"
get_dates(x, "right")
#> [1] "2019-04-01" "2019-05-01" "2019-06-01"
# Return dates by number of days from the first date get_dates(x, count_days = TRUE)
#> [1] 0 31 61
get_dates(incidence(-5:5), count_days = TRUE)
#> [1] 0 1 2 3 4 5 6 7 8 9 10
