rli.predict

Prediction of Red List Index.

Linearly interpolates and extrapolates RLI values to any years.

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

`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

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.

A matrix with the RLI values and confidence limits.

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)
