otherStrand {tilingArray}R Documentation

Return the name of the opposite strand

Description

Return the name of the opposite strand

Usage

otherStrand(x)

Arguments

x Character vector whose elements are "+" or "-".

Details

This is a rather trivial convenience function.

An alternative would be to code strands with integers -1 and +1, in which case the inversion would be a trivial builtin operation. However, many genomic databases and input data files use the character string / factor notation.

Value

Character vector of same length as x, with strands reversed.
