In ptaconet/rtunaatlas: IRD Sardara Tuna Atlas R facilities

Creates a continious calendar

Description

Creates a continious calendar according to input parameters : first and final date of the calendar, temporal resolution and temporal resolution unit

Usage

create_calendar(firstdate,finaldate,resolution,unit)

Arguments

firstdate	character string first date of the calendar, format : YYYY-MM-DD
finaldate	character string final date of the calendar, format : YYYY-MM-DD
resolution	real temporal resolution of the calendar in day, month or year (see: temporal_reso_unit). Note: for 1/2 month put temporal_reso=1/2 and temporal_reso_unit="month" , type = integer;
unit	character string temporal resolution unit. accepted value : "day" "month" "year"

Details

Values for unit can be: "day","month","year".

The algorithm can create a mi-month calendar : first period between 1st and 15th of a month, second period between 16th and the end of the month. For this set resolution=0.5 and unit="month"

Value

A dataframe with two columns : "time_start" (starting date of the period) and "time_end" (ending date of the period).
