EstimateBreed (version 1.0.2)

hw: Hectolitre weight of cereals

Description

Useful function for characterizing the hectolitre weight (HW) of experiments with cereals.

Usage

hw(GEN, HL, crop = "trit", stat = "all")

Value

Returns the estimated value for the hectoliter weight considering the selected cereal.

Arguments

GEN

The column with the genotype name

HL

Weight obtained on a 1qt lt scale, as determined by the Rules for Seed Analysis (RAS), Ministry of Agriculture, Livestock and Supply (2009).

crop

Argument for selecting culture. Use 'trit' for wheat, 'oat' for white oats, 'rye' for rye and 'barley' for barley

stat

Argument to select the function output type. Use 'all' to estimate the HW for all replicates, or 'mean' to extract the mean for each genotype.
