doIfreqR Documentation

Create indices that are sampled at various frequencies

Description

Given an index (historical period and projected period) this function creates sparsity in the projected index to simulate varying frequency (intensity) of data collection.

Usage

doIfreq(I_hist, I_freq, LHYr, CurYr, Year)

Arguments

I_hist

Vector of real numbers, concatinated observed (historical) and simulated (projected) indices.

I_freq

Positive integer. The frequency of index sampling (e.g. 1 is every year, 2 is every 2 years - a gap every 2 years in the projected, simulated data).

LHYr

Positive integer, a year (e.g. 2023), the last historical year, demarks the historical period where observations have been collected from the projected period where sparsity is to be simulated.

CurYr

Positive integer, a year (e.g. 2043), the most recent year of the simulation.

Year

Vector of positive integers (as long as I_hist), the years corresponding with I_hist.

Value

A thinned ector I_hist long of index observations.
