DOEpro 2.0.1

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.
• \value is documented for the exported DESIGNS and TRANS objects.
• 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().

DOEpro 2.0.0

First public release.

• Analyses eleven designs: completely randomised, randomised complete block, Latin square, factorial CRD and RCBD (two to four factors), split-plot, strip-plot, and pooled (combined) analysis over environments for both a single treatment factor and factorial treatments.
• Chooses the correct error term for every comparison. A split plot reports its four distinct standard errors of a difference, the two mixed comparisons using a Satterthwaite-weighted t.
• Pooled analyses test each treatment effect against its own interaction with the environment, check the homogeneity of the error variances across environments (Bartlett), and break a significant environment by treatment interaction down environment by environment.
• Analyses several response variables at once, each with its own transformation.
• Screens the data against the assumptions and advises on a variance-stabilising transformation; nine transformations are available, with means reported back on the original scale.
• Grouping letters are shown only where the F-test is significant.
• Six post-hoc procedures: Fisher’s protected LSD, Bonferroni, Tukey HSD, Duncan, Student-Newman-Keuls and Scheffe.
• Produces a downloadable HTML report carrying the DOEpro citation.
• Runs in the browser at https://doepro.pages.dev with no installation.
