Returns the projections for all selected models (same as in biomod2
)

for details.
list
object returned by ecospat.ESM.Modeling
A set of explanatory variables onto which models will be projected. It could be a data.frame
, a matrix
, or a SpatRaster
object. Make sure the column names (data.frame
or matrix
) or layer Names (SpatRaster
) perfectly match with the names of variables used to build the models in the previous steps.
A name for the new.env object. If not specified (default) the name of the new.env object will be used. It is necessary to specify a unique name when projecting various new.env objects in a loop.
vector of models names choosen among 'GLM', 'GBM', 'GAM', 'CTA', 'ANN', 'SRE', 'FDA', 'MARS', 'RF','MAXENT', "MAXNET" (same as in biomod2
)
#a character vector (either 'all' or a sub-selection of model names) that defines the models kept for building the ensemble models (might be useful for removing some non-preferred models)
Logical. If TRUE, the parallel computing is enabled

The basic idea of ensemble of small models (ESMs) is to model a species distribution based on small, simple models, for example all possible bivariate models (i.e. models that contain only two predictors at a time out of a larger set of predictors), and then combine all possible bivariate models into an ensemble (Lomba et al. 2010; Breiner et al. 2015).
The ESM set of functions could be used to build ESMs using simple bivariate models which are averaged using weights based on model performances (e.g. AUC) accoring to Breiner et al (2015). They provide full functionality of the approach described in Breiner et al. (2015).
The name of new.env
must be a regular expression (see ?regex)
