Evaluate a Feature at a Given Index

Evaluates the feature function at the specified index (1-based, as is standard in R). Internally converts to 0-based indexing for C++.

Usage

maxent_feature_eval(feature, index)

Arguments

feature

External pointer to a Feature C++ object.

index

1-based integer index into the data vector.

Value

Numeric scalar: the feature value at that index.

Examples

vals <- c(0, 5, 10)
f <- maxent_linear_feature(vals, "temp")
maxent_feature_eval(f, 2)  # 5/10 = 0.5
#> [1] 0.5
