Workshop 2
Efficient Trial Design with speedIllustration of efficient trial design with *speed*

Date: Wednesday, 11 November 2026
Time: 11:00 - 13:00
Venue: QT Perth, Murray Room

Chairs: Sam Rogers and Wasin Pipattungsakul

Summary

speed is an R package from AAGI-AU that generates spatially optimised, model-free experimental designs. In this hands-on workshop, we’ll explain what model-free means in practice, give a conceptual overview of how speed works, then walk through:

  • Standard designs such as RCBD and split-plot
  • Row-column, p-rep, and multi-environment trial (MET) designs
  • Incorporating a relationship matrix or covariates
  • Writing your own objective functions

Participants should be comfortable in R.

Please bring a laptop with speed installed:

if (!require("pak", quietly = TRUE)) install.packages("pak")
pak::pak("biometryhub/speed")
