Bayesian AMMI and GGE analysis in a web browser

bam_app() starts the application of bayesammi: load a trial (the example Maiz or a CSV file with one row per plot), fit the Bayesian AMMI or GGE model, check convergence, draw the biplot with HPD regions, and turn the posterior into decisions (which genotype wins where, probabilities of superior performance and stability, ranks, Bayesian stability, predictions of missing cells), and compare models. Every page shows an interpretation computed from the results (bam_interpret()), the output as R prints it, formatted tables, plots and the R code that repeats the analysis, each with a Copy button.

Usage

bam_app(launch.browser = interactive(), ...)

bam_app_object()

Arguments

launch.browser: passed to shiny::runApp(): TRUE (default in an interactive session) opens the application in the web browser.
...: further arguments to shiny::runApp(), such as port.

Value

bam_app() is called for its side effect and returns the value of shiny::runApp() when the application is closed; bam_app_object() returns the application object (for shiny::runApp(), shiny::testServer() or deployment on a server).

Details

The application needs the suggested packages shiny, bslib and DT. Plots are sent to the browser as WebP images when magick is installed (smaller than PNG; PNG otherwise) and can be downloaded as PNG, PDF or WebP. Text is set in IBM Plex Sans and output in IBM Plex Mono when the browser can reach Google Fonts, in the system fonts otherwise.
