buffering {blockCV}

Use distance (buffer) around records to separate train and test folds

Description

This function is deprecated and will be removed in future updates! Please use cv_buffer instead!

Usage

buffering(
  speciesData,
  species = NULL,
  theRange,
  spDataType = "PA",
  addBG = TRUE,
  progress = TRUE
)

Arguments

speciesData

A simple features (sf) or SpatialPoints object containing species data (response variable).

species

Character. Indicating the name of the field in which species data (binary response i.e. 0 and 1) is stored. If speceis = NULL the presence and absence data (response variable) will be treated the same and only training and testing records will be counted. This can be used for multi-class responses such as land cover classes for remote sensing image classification, but it is not necessary. Do not use this argument when the response variable is continuous or count data.

theRange

Numeric value of the specified range by which the training and testing datasets are separated. This distance should be in metres no matter what the coordinate system is. The range can be explored by spatialAutoRange.

spDataType

Character input indicating the type of species data. It can take two values, PA for presence-absence data and PB for presence-background data, when species argument is not NULL. See the details section for more information on these two approaches.

addBG

Logical. Add background points to the test set when spDataType = "PB".

progress

Logical. If TRUE a progress bar will be shown.
