Description
Dear maintainers,
I would like to suggest adding the CRAN package pwr4exp to the sample-size/power paragraph of the task view.
Package:
pwr4exp — Power Analysis for Research Experiments
https://CRAN.R-project.org/package=pwr4exp
Suggested addition:
Package pwr4exp deals with power calculations for experiments analyzed using linear mixed models, including randomized block, split-plot, Latin square, repeated-measures, and other user-defined experimental designs.
Rationale:
This would complement the existing paragraph on sample-size and power packages. Package pwr4exp adds support for power analysis in linear mixed-model settings, especially those common in agricultural science, including designs with blocking, random effects, hierarchical error structures, and correlated residuals.
Thank you for considering this addition.

Research direction
Start in the ExperimentalDesign task view's sample-size and power paragraph and review how existing packages are described. Add pwr4exp with its CRAN link and the suggested summary of its linear mixed-model power-analysis support, then verify that the paragraph remains consistent with the surrounding task-view entries.
