indexFeats: Re-index features

In FamilyRank: Algorithm for Ranking Predictors Using Graphical Domain Knowledge

Description

Re-index features based on number to rank. Called by familyRank.

Usage

indexFeats(scores, graph, n.rank = NULL)

Arguments

scores	A numeric vector of empirical feature scores.
graph	A matrix or data frame representation of a graph object.
n.rank	Number of features to rank.

Details

This function is used to re-index features for the Family Rank algorithm. The function takes in the scores for all features, and returns scores for the top n.rank features. It also takes in the full domain knowledge graph and returns the subgraph that only includes interactions between the top n.rank features. Finally, it re-indexes the top features in both the score vector and domain knowledge graph to 1:n.rank.

Value

Returns a named list with re-indexed domain knowledge graph (graph.w), re-indexed scores (score.w), a mapping between original and new indices (loc.map), and the number of features to rank (n.rnak).

Note

indexFeats is not meant to be called alone. It is designed as a helper function for familyRank.
