Update an sdmTMB model — update.sdmTMB • sdmTMB

This method updates an sdmTMB model with new arguments, automatically handling the mesh object to avoid environment issues when loading models from saved files.

Usage

# S3 method for class 'sdmTMB'
update(object, formula., ..., evaluate = TRUE)

Arguments

object: An sdmTMB model object
formula.: Optional updated formula
...: Other arguments to update in the model call
evaluate: If TRUE (default), the updated call is evaluated; if FALSE, the call is returned unevaluated

Value

An updated sdmTMB model object (if evaluate = TRUE) or an unevaluated call (if evaluate = FALSE)

Examples

mesh <- make_mesh(pcod_2011, c("X", "Y"), cutoff = 20)
fit <- sdmTMB(density ~ 1, data = pcod_2011, mesh = mesh,
  family = tweedie(link = "log"))
fit2 <- update(fit, family = delta_gamma())
