Builds SDM formulae — buildFormula • webSDM

Builds the formula of both the abiotic and biotic terms to fit a single species SDM based on the input parameters. The function is called inside the SDMfit function

buildFormula(
  form.init,
  species,
  sp.formula = NULL,
  sp.partition = NULL,
  useBRMS
)

Arguments

form.init: The abiotic part of the formula
species: The preys (or predators) of the focal species
sp.formula: optional parameter for composite variables. See ?trophicSDM
sp.partition: optional parameter to specify groups of species for composite variables. See ?trophicSDM
useBRMS: whether brms is used (TRUE if penal = "coeff.signs" and method = "stan_glm).
