init_dates_dataframe function

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.

Returns

A tibble with dates.
