Stripping Prefix from Gene IDs — h_strip

This helper function removes the prefix and possible delimiter from a vector of gene IDs, such that only the digits are returned.

Usage

h_strip_prefix(gene_ids, prefix)

gene_ids: (character)
original gene IDs including prefix and optional delimiter before the digits.
prefix: (string)
common prefix to be stripped away from gene_ids.

Character vector that contains only the digits for each gene ID.

This is currently used to strip away the GeneID prefix from Entrez gene IDs so that they can be queried from BioMart

h_strip_prefix(c("GeneID:11185", "GeneID:10677"), prefix = "GeneID")
#> [1] "11185" "10677"
