i.uwwi: Un-weighted Interaction Weather Indices

Description

Converts the weekly interaction of two weather variable into yearly weighted interaction weather indices

Usage

i.uwwi(y, weatherp1, weatherp2)

Value

A vector of interaction weather indices

Arguments

y

A vector of yearly yield data for t years

weatherp1

Weekly weather data for t years as vector of first weather variable(total observations= number of years*number of weeks in each year)

weatherp2

Weekly weather data for t years as vector of second weather variable(total observations= number of years*number of weeks in each year)
