Analysis of Designed Agricultural Experiments
Overview
A 'shiny' application and supporting functions for the analysis of designed agricultural experiments, following the procedures set out by Gomez and Gomez (1984, ISBN:9780471870920). Handles completely randomised, randomised complete block, Latin square, factorial (up to four factors), split-plot and strip-plot designs, and pooled (combined) analysis over environments including factorial treatments, after Yates and Cochran (1938) doi:10.1017/S0021859600050978; analyses several response variables simultaneously; recommends and applies variance-stabilising transformations using the profile likelihood of Box and Cox (1964) doi:10.1111/j.2517-6161.1964.tb00553.x; reports standard errors and critical differences for every legitimate comparison, including the four distinct comparisons of a split plot, the mixed ones using the approximation of Satterthwaite (1946) doi:10.2307/3002019; and produces publication-format tables of means, diagnostic plots and a written interpretation.
Changes made in response to the CRAN review of version 2.0.0.
- Software names are quoted and the methods are referenced with their DOIs in the package description.
\valueis documented for the exportedDESIGNSandTRANSobjects.demo_data()no longer sets a random seed. The example datasets are now built from a stored vector of deviates, so they are identical on every machine and the user's random number stream is left untouched.- The plain-text report saves and restores the user's graphical parameters with an immediate
on.exit().
