Rename a ranked gene list from gene symbols to ENTREZ identifiers

Source: R/enrichment_analysis.R
rename_ranking_to_entrezid.Rd

rename_ranking_to_entrezid() keeps each score attached to its own gene.

Usage

rename_ranking_to_entrezid(ranked_genes)

Arguments

ranked_genes

A named numeric vector, named by gene symbol.

Value

The same scores, named by ENTREZ identifier and sorted decreasingly.

Details

The symbol to identifier mapping drops genes it cannot resolve and can return several identifiers for one symbol, so the scores have to be matched by name. Renaming the vector positionally would silently attach each score to the wrong gene as soon as a single symbol failed to map.
