Description

Pull out a specified set of chromosomes and/or LOD columns from scanone output.

Usage

# S3 method for scanone
subset(x, chr, lodcolumn, …)

Arguments

x

An object of class scanone, output from scanone.

chr

Optional vector specifying which chromosomes to keep. This should be a vector of character strings referring to chromosomes by name; numeric values are converted to strings. Refer to chromosomes with a preceding - to have all chromosomes but those considered. A logical (TRUE/FALSE) vector may also be used.

lodcolumn

A vector specifying which LOD columns to keep (or, if negative), omit. These should be between 1 and the number of LOD columns in the input x.

…
