trigger (version 1.18.0)

trigger.export2cross-methods: Export Trigger data to R/qtl's cross class object

Description

trigger.export2cross exports trigger data from triggerobj to a cross format for Trait-Trigger analysis. See trigger.trait for details.

Usage

"trigger.export2cross"(triggerobj, plotarg = TRUE, verbose = TRUE, warning = FALSE)

Arguments

triggerobj

An object of class trigger.

plotarg

Logical. If TRUE, the function plots the default plot from the R/qtl package while reading in the genotype data.

verbose

Logical. If TRUE, the function lists the default output from the R/qtl package while reading in the genotype data.

warning

Logical. If FALSE, the function suppresses warnings output from the R/qtl package while reading in the genotype data.

Value

R/qtl package.

Details

The trigger.export2cross command writes a csv format file “geno_trait_data.csv” to the working directory and reads it using the read.cross command.
