Check Dates for Sequentialness and Completeness — check_date

Used to check vectors of dates mainly to ensure that weather data are complete. Invisibly returns a NULL value if no errors are found, else issues a warning() with an informative message providing the user with missing date values in the sequence and the optional location name if it's provided.

check_date_seq(x, y = NULL)

Arguments

x: A vector of dates.
y: A vector of values with location name, used for warning message.

Value

No return value, called for side effects. Errors if the dates provided are not sequential.

Examples


# passes
x <- seq(as.Date("2021-01-01"), as.Date("2021-01-31"), by = "1 day")
y <- "BA"
check_date_seq(x = x, y = y)
#> Warning: The vectors do not contain sequential dates, , is/are missing.
#> non_sequential_date

# fails
x <- c(seq(as.Date("2021-01-01"), as.Date("2021-01-31"), by = "1 day"),
       seq(as.Date("2021-02-02"), as.Date("2021-02-28"), by = "1 day"))
y <- "BA"
check_date_seq(x = x, y = y)
#> Warning: The vectors do not contain sequential dates, 2021-02-01, is/are missing for BA.
#> non_sequential_date
