Mapping function between time-slices and day of the year

Mapping function between time-slices and day of the year

Mapping function between time-slices and hour

Mapping function between time-slices and month

Usage

tsl2year(tsl, return.null = TRUE)

tsl2yday(tsl, return.null = TRUE)

tsl2hour(tsl, return.null = TRUE, pattern = "h[0-9]++")

tsl2month(tsl, format = tsl_guess_format(tsl), return.null = TRUE)

Arguments

tsl

character vector with time slices

return.null

logical, valid for the cased then all values are NA, then NULL will be returned if return.null = TRUE,

format

character, the time slices format

Value

Integer vector of years, the same length as the input vector

Integer vector of days of the year, the same length as the input vector

Integer vector of hours, the same length as the input vector

Integer vector of months, the same length as the input vector

Functions

• tsl2year(): Extract year from time-slices

• tsl2yday(): Extract the day of the year from time-slices

• tsl2hour(): Extract hour from time-slices

• tsl2month(): Extract month from time-slices
