getChrOrder: Get chromosome order from a string of chromosome/contig names

In karyotapR: DNA Copy Number Analysis for Genome-Wide Tapestri Panels

Get chromosome order from a string of chromosome/contig names

Description

getChrOrder() takes a string of chromosome or contig names and returns the indices of the string in typical chromosome order, i.e. 1 through 22, X, Y. Contig names that do not match 1:22, X, or Y are sorted numerically and alphabetically (with numbers coming first), and added to the end of the order. The output string can then be used to sort the input string into typical chromosome order.

Usage

getChrOrder(chr.vector)

Arguments

chr.vector

Character vector of chromosome or contig names.

Value

A numerical vector of the input vectors indices in chromosome order.

Examples

chr.order <- getChrOrder(c(1, "virus", 5, "X", 22, "plasmid", "Y"))
ordered.vector <- c(1, "virus", 5, "X", 22, "plasmid", "Y")[chr.order]
