GRaF provides functions to fit, visualise, and predict from Gaussian process models for binary data, with an emphasis on species distribution models. The principle function is graf
which returns a graf
object, which can be manipulated using plot
, print
and predict
methods among others.
GRaF is under active development and future releases will enable a range of additional methods, which may (or may not) include: models for count data, spatially and temporally explicit models, the ability to limit interactions between covariates, multi-species models and input and output of raster imagery. Please feel free to contact the maintainer with bug reports and suggestions!
