powergrid 0.5.2

Corrected listing in readme and vignette.

powergrid 0.5.1

Small update, making readme in line with CRAN status package.

powergrid 0.5.0 (2025-09-30)

• Added Richard Charles Allen as contributor and maintainer.
• Fixed one typo in description.

powergrid 0.4.0

• Omitted all settings of par(), including graphics::layout() (PowerPlot and GridPlot)
• Argument shades_legend removed as argument to PowerPlot. The related function to add a legend to the grey scale is omitted too. This legend is difficult to position without setting par. Also, the use of such legend is very limited, since the eye is notoriously bad in seeing the equality or difference between shades when they do not share a border. (PowerPlot)
• Omitted (conditional) set.seed() in PowerGrid. This seed was set for cases where there happens to be no .Random.seed yet. Slightly tweaky circumvented by always drawing one uniform number before doing anything.

powergrid 0.3.0

• performed all checks as listed in issue #55 Release powergrid 0.3.0

powergrid 0.2.1

• only typos

powergrid 0.2.0

This is a large, but still minor update. Some arguments have been renamed and one function has a new name. Vignette has been improved greatly, and all documentation has been updated and extended. Cross-referencing in Documentation is improved. Warnings and documentation is more consistent now.

Not that this is a Beta release. Use remotes::install_github("SwissClinicalTrialOrganisation/powergrid", ref = "v0.2.0") to install it. The package is very soon to be sumbitted to CRAN. No changes at the user side are planned.

Breaking Changes

• SummarizeIterations() replaces the older SummarizeSims. Iterations may, but must not be simulations. Language is consistency adjusted throughout the package. In documentation, as well as in attributes of power_array objects, "sim" is, where relevant, replaced by "iter".
• Central argument names have changed in Example, PowerPlot, GridPlot, AddExample and FindTarget:
  • find_lowest replaces find_min
  • target_at_least replaces minimal_target
  • target_value replaces target
• Compatibility with sse package was omitted. see is offline and is not updated. Keeping all working with eventual sse output was too error-prone for little use.

Improvements user level

• All help files were improved
• Vignette was extended and improved
• Tests included! (thanks Richard!)
• Input handling of all functions and respective errors and warnings was improved.
• PowerPlot and Example naturally deal with one-dimensional power_array object. PowerPlot has a special figure to represent the one-dimensional situation.

Improvements under the hood

• The plotting of examples inside PowerPlot() is now handled by AddExample.
• Summarizing across dimenstions inside power_grid is now performed by SummarizeIterations() (Thanks Richard!)

bug fixes

• A multitude of bugs were fixed
