Apply a fitted mapper to values

Alias to [predict_mapper()] that mirrors the terminology used by the dense rendering helpers.

Usage

apply_mapper(fitted_mapper, values, ...)

Arguments

fitted_mapper

Mapping object returned by [fit_mapper()].

values

Numeric vector or matrix of source-space values.

...

Optional backend-specific arguments (e.g. reliabilities).

Value

Numeric vector or matrix of mapped values.

Examples

spec <- dkge_mapper("knn", k = 3, sigx = 1)
subj_points <- matrix(rnorm(12 * 3), 12, 3)
anchor_points <- matrix(rnorm(6 * 3), 6, 3)
fitted <- fit_mapper(spec, subj_points = subj_points, anchor_points = anchor_points)
out <- apply_mapper(fitted, rnorm(nrow(subj_points)))
length(out)
#> [1] 6
