MSD: Mid Summer Drought

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

Description

Calculate different statistics of the mid summer drought from a RasterBrick or a Time Series.

The input must be in the form of daily data, with the first data point being January 1st of a respective year.

If x is a RasterBrick, then the output is a RasterBrick with a data point for each year. If you would like to find a statistical value of the new rasterbrick, it is recommended to use

r <- raster::calc(x, mean)

If the index vector from lpdates2/lpdates4 is not saved as 'dated'/'dated6', a function will have to be created to use it in raster::calc.

Usage

MSD(x, dated1=dated, dated4=dated6, fun="duration")

Arguments

x	RasterBrick or TimeSeries
fun	Specify what values to be pulled from the function. Options include 'duration', 'intensity', 'max1', 'max2', 'min', and 'mindex'.
dated	Index of Dates from the lpdates2 function (should be saved as 'dated')
dated6	Index of Dates from the lpdates4 function (should be saved as 'dated')

Value

RasterBrick or TimeSeries of Yearly data

Examples

# using RasterBricks
r<-raster::calc(x, MSD)

# using TimeSeries
r<-MSD(x)
