Initialises a tibble with dates

Creates a tibble with rows for each date from 'yrstart' to 'yrend' in 'yyyy-mm-dd' format. Intervals of dates are specified by argument 'freq'. ddf <- init_dates_dataframe(2000, 2003, startmoy=1, startdoy=1, freq="days", endmoy=12, enddom=31, noleap=FALSE)

init_dates_dataframe(
  yrstart,
  yrend,
  startmoy = 1,
  startdoy = 1,
  freq = "days",
  endmoy = 12,
  enddom = 31,
  noleap = FALSE
)

Arguments

yrstart

An integer defining the start year of dates covered by the dataframe.

yrend

An integer defining the end year of dates covered by the dataframe.

startmoy

An integer defining the start month-of-year of dates covered by the dataframe. Defaults to 1.

startdoy

An integer defining the start day-of-year of dates covered by the dataframe. Defaults to 1.

freq

A character string specifying the time steps of dates (in rows). Defaults to "days". Any of "days", "months", "years". If freq = "months" the 15\(^{th}\) day of the months is used as date, and if freq = "years" the 1\(^{st}\) of January of each year is returned.

endmoy

An integer defining the end month-of-year of dates covered by the dataframe. Defaults to 12.

enddom

An integer defining the end day-of-year of dates covered by the dataframe. Defaults to 31.

noleap

Whether leap years are ignored, that is, whether the 29\(^{th}\) of February is removed. Defaults to FALSE.

Value

A tibble with dates.
