Check the balance of presences vs pseudoabsences among splits

Usage

check_splits_balance(splits, .col)

Arguments

splits: the data splits (an rset or split object), generated by a function such as spatialsample::spatial_block_cv()
.col: the column containing the presences

Value

a tibble of the number of presences and pseudoabsences in the assessment and analysis set of each split (or training and testing in an initial split)

Examples

lacerta_thin <- readRDS(system.file("extdata/lacerta_climate_sf.RDS",
  package = "tidysdm"
))
lacerta_cv <- spatial_block_cv(lacerta_thin, v = 5)
check_splits_balance(lacerta_cv, class)
