hw {EstimateBreed} | R Documentation |
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")
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. |
Value
Returns the estimated value for the hectoliter weight considering the selected cereal.
