Set plot-level random effects for one or more species — set_random

Populates the $random_effects slot inside each species entry of an ipm_parameters object. Engines (lambda(), project()) default to c(0, 0, 0) for any species whose slot is NULL.

Usage

set_random_effects(pars, values, species = NULL)

Arguments

pars: An ipm_parameters object.
values: A numeric vector of length 3 (growth, survival, recruitment offsets), applied to all species named in species; or a named list keyed by species ID, each element a numeric vector of length 3.
species: Character vector of species IDs. Used only when values is a numeric vector; ignored when values is a named list. If NULL and values is a numeric vector, applies to all species.

Value

The modified ipm_parameters object.

Examples

df <- data.frame(size_mm = c(150, 200, 350),
                 species_id = "ABIBAL",
                 plot_size  = 1000)
s     <- stand(df)
mod   <- species_model(s)
pars  <- parameters(mod, draw = "mean")
pars2 <- set_random_effects(pars, values = c(0, 0, 0))
