reverse_complement: Reverse complement a DNA/RNA sequence (generic 'ggDNAvis'...

In ggDNAvis: 'ggplot2'-Based Tools for Visualising DNA Sequences and Modifications

Reverse complement a DNA/RNA sequence (generic ggDNAvis helper)

Description

This function takes a string/character representing a DNA/RNA sequence and returns the reverse complement. Either DNA (A/C/G/T) or RNA (A/C/G/U) input is accepted.

By default, output is DNA (so A is reverse-complemented to T), but it can be set to output RNA (so A is reverse-complemented to U).

Usage

reverse_complement(sequence, output_mode = "DNA")

Arguments

sequence	character. A DNA/RNA sequence (A/C/G/T/U) to be reverse-complemented. No other characters allowed. Only one sequence allowed.
output_mode	character. Either "DNA" (default) or "RNA", to determine whether A should be reverse-complemented to T or to U.

Value

character. The reverse-complement of the input sequence.

Examples

reverse_complement("ATGCTAG")
reverse_complement("UUAUUAGC", output_mode = "RNA")
reverse_complement("AcGtU", output_mode = "DNA")
reverse_complement("aCgTU", output_mode = "RNA")
