lpdates2: Pulling Dates

In kjoseph654/MSD: What the Package Does (One Line, Title Case)

Description

This function pulls the dates that correspond with the Mid Summer Drought, and is used in conjuction with the MSD function.

Usage

lpdates2(x, year1=1981, date1="05-01", date2="06-01", date3="08-31", date4="10-31")

Arguments

x	Date vector
year1	The year the Date vector starts on
date1	Start index to find first onset date
date2	End index to find first onset date
date3	Start index to find second onset date
date4	End index to find second onset date

Value

A vector of indexes that correspond to the four dates every year, with respect to the start date.

NOTE: It would be significantly easier to save the output as a variable called 'dated', especially when using rasters so that you do not have to create an intermediate function.

Examples

dates<-seq(from = as.Date("1981-01-01"), to = as.Date("2020-12-31"), by = "day") 
lpdates2(dates, year1=1981, date1="05-01", date2="06-01", date3="08-31", date4="10-31")
