Generate Features from Environmental Variable Data

Automatically generates all configured feature types from one or more environmental variable vectors.

Usage

maxent_generate_features(
  data,
  types = c("linear", "quadratic", "product", "threshold", "hinge"),
  n_thresholds = 10L,
  n_hinges = 10L
)

Arguments

data

Named list of numeric vectors, one per environmental variable.

types

Character vector of feature types to generate. Valid values: "linear", "quadratic", "product", "threshold", "hinge". Defaults to all types.

n_thresholds

Integer; number of threshold knots per variable (default: 10).

n_hinges

Integer; number of hinge knots per variable (default: 10).

Value

Named list of external pointers to Feature C++ objects.

Examples

env_data <- list(
  temperature   = c(15, 20, 25, 18, 22),
  precipitation = c(100, 200, 150, 80, 300)
)
features <- maxent_generate_features(env_data, types = c("linear", "hinge"))
length(features)
#> [1] 42
