gexp 1.1-0

Internal

• Added R/gexp-utils.R with shared helpers for error simulation, response assembly, data-frame binding, result packing, and contrast merging; all nine gexp.* methods now call these helpers (no change in exported behaviour).
• Extended gexp-utils.R with helpers for default fixed effects, block effects, treatment/contrast construction, row/column LSD layout, and interaction terms; RCBD and LSD methods now use these (behaviour unchanged).
• Added split-plot helpers (.gexp_zformula, .gexp_Z, .gexp_spe_finish) for whole-plot Z matrix construction and the shared SPE response tail; gexp.spe_crd, gexp.spe_rcbd, and gexp.spe_lsd now use them (behaviour unchanged).
• Added R/gexp-plot-utils.R with shared helpers for layout centres, static/dynamic frames, grids, labels, and locator text; all nine plot.gexp.* methods now use them.
• Fixed plot label coordinates when row and column centre vectors differ in length (e.g. factorial RCBD and split-plot layouts).
• Fixed LSD rowl/coll when passed as bare character vectors (default names Row/Column); named lists remain the documented form.
• Fixed factorial and CRD plot label placement (overlapping treatment labels in empty cells) by restoring correct rep() coordinates in gexp-plot-utils.R.
• Fixed SIMPLE RCBD plot layout (block labels misaligned with rows) by restoring row/column centre assignment in plot.gexp.simple_rcbd.R.

Code style

• Reformatted all sources under R/ for readability (aligned named arguments, consistent spacing, and line breaks at commas) without changing program logic.
• Re-applied the same formatting to gexp-utils.R, gexp-plot-utils.R, and all gexp.* / plot.gexp.* methods after the internal refactor (multi-argument calls broken at commas, named arguments aligned).
• Renamed vignettes/intro.Rmd to vignettes/gexp-overview.Rmd with conventional R code spacing in examples (aligned with standard style, distinct from /R sources).
• Revised vignette prose: improved English and translated remaining Portuguese passages.

Documentation

• Added demo/ with nine runnable examples (demo(package = "gexp")) covering every type x design combination (SIMPLE, FE, SPE x CRD, RCBD, LSD); all demos use explicit fl, blkl, rowl, and coll labels where applicable.
• Standardized author names to scientific notation (Faria, J. C.; Allaman, I. B.) across the package.
• Migrated package history from ChangeLog to NEWS.md.
• Refactored README.md to match the documentation standard used in sibling packages (badges, features, installation, quick start, project layout, contributing, and roadmap).
• Updated DESCRIPTION metadata (Authors@R, BugReports, reformatted Description, License: GPL-2, R (>= 4.1.0)); maintainer remains Allaman, I. B.
• Removed prebuilt vignette artifact inst/doc/intro.html from the repository.

Infrastructure

• Added .Rbuildignore to exclude version-control and check artefacts from package builds.
• Added .gitignore and .Rbuildignore rules to keep locally rendered vignettes/*.html out of the repository.
• Added a testthat suite under tests/testthat/ with smoke tests for core design generation, summary, print, and plot.

gexp 1.0-21 (2023-06-21)

• Adjusted files as required by CRAN.

gexp 1.0-2

• Changed character columns to factors in gexp.fe_lsd() and gexp.simple_lsd().

gexp 1.0-1 (2020-04-02)

• Fixed a bug in gexp.spe_lsd(): added stringsAsFactors = TRUE when calling data.frame(), matching the default change in newer R versions (stringsAsFactors = FALSE).

gexp 1.0-0 (2019-06-14)

• Split the former type argument into two arguments: type (SIMPLE, FE, SPE) and design (CRD, RCBD, LSD).
• Added new methods for generic gexp: simple_crd, simple_rcbd, simple_lsd, fe_crd, fe_rcbd, fe_lsd, spe_crd, spe_rcbd, and spe_lsd.
• Removed nrand and random from the gexp functions; added random to the plot functions instead.
• Added internal helpers: makeInteraction, makeContrasts, makeTreatments, and makeXBeta.
• Optimized code across all functions.
• Updated .Rd files, vignettes, NAMESPACE, and DESCRIPTION to reflect the new API.
• Minor documentation corrections.

gexp 0.1-6

• Fixed incorrect calculations for quantitative factors in RCBD and LSD designs.

gexp 0.1-5

• Updated NAMESPACE for consistency with the package API.

gexp 0.1-4 (2019-04-14)

• Minor documentation corrections.
• Released to CRAN.

gexp 0.1-3

• All plot functions now restore graphics parameters changed via par(xaxs = "i", yaxs = "i") when returning to the device.
• Minor changes to the source code of some functions.

gexp 0.1-2

• Corrected the package name typo (gerexp → gexp) in gexp-package.Rd.
• Corrected the date entry for version 0.1-1 in the change log.

gexp 0.1-1

• Fixed encoding issues in some documentation (.rmd) files that caused build failures.
• General documentation improvements.

gexp 0.1-0

• Initial release of the gexp package.
