Evaluate rank-weight for many targets (batch)

Usage

rank_weight_eval_batch(spec, R, ctx = NULL)

Arguments

spec

Rank-weight spec (see is_rank_weight()).

R

Integer matrix (n x m), each column a permutation of 1..n.

ctx

Optional context (if the spec uses it).

Value

Numeric matrix (n x m).

Examples

rw <- as_rank_weight(function(r) rep(1 / length(r), length(r)))
rank_matrix <- cbind(c(1L, 2L, 3L), c(2L, 1L, 3L))
rank_weight_eval_batch(rw, rank_matrix)
