标题： hassediagrams:an R package that generates the Hasse diagram of the layout structure and the restricted layout structure

摘要： 随着现代统计软件的出现，复杂的实验设计现在在许多研究领域中被常规使用。 未能正确识别实验设计的结构可能导致错误的模型选择和误导性的推论。 本文描述了R中的hassediagrams包，该包确定设计的结构，由布局结构总结，并生成布局结构的哈斯图。 通过考虑进行的随机化，结合布局结构，可以定义一组随机化对象，这些对象形成受限的布局结构。 此结构也可以通过哈斯图的推广来可视化。 受限布局结构中的对象可用于确定应包含在统计模型中的项。 因此，使用该过程确保了模型选择的一致性，因为采用了系统的方法来生成模型。 显示英文摘要

摘要： With the advent of modern statistical software, complex experimental designs are now routinely employed in many areas of research. Failing to correctly identify the structure of the experimental design can lead to incorrect model selection and misleading inferences. This paper describes the hassediagrams package in R that determines the structure of the design, summarised by the layout structure, and generates a Hasse diagram of the layout structure. By considering the randomisation performed, in conjunction with the layout structure, a set of randomisation objects can be defined that form the restricted layout structure. This structure can also be visualised using a generalisation of the Hasse diagram. Objects in the restricted layout structure can be used to identify the terms to include in the statistical model. The use of the procedure thus ensures consistency of model selection due to the systematic approach taken to generate the model.
