rli.predict: Prediction of Red List Index.

In red: IUCN Redlisting Tools

Prediction of Red List Index.

Description

Linearly interpolates and extrapolates RLI values to any years.

Usage

rli.predict(rliValue, from = NA, to = NA, rliPlot = FALSE)

Arguments

rliValue	Should be a vector with RLI values and names as the corresponding year numbers.
from	Starting year of the sequence to predict.
to	Ending year of the sequence to predict.
rliPlot	Plots the result

Details

The IUCN Red List Index (RLI) (Butchart et al. 2004, 2007) reflects overall changes in IUCN Red List status over time of a group of taxa.

Value

A matrix with the RLI values and confidence limits.

Examples

rliValue <- c(4.5, 4.3, 4.4, 4.2, 4.0)
names(rliValue) <- c(2000, 2004, 2008, 2011, 2017)
rli.predict(rliValue, 1990, 2020)
