dimensio 0.10.0

New classes and methods

• Add export() to create a Zip archive of all results in CSV format.

Internals

• Translate into French.
• Compute the position and draw only the labels in the plotting region.
• Add type checking of arguments.

dimensio 0.9.0 (2024-08-26)

New classes and methods

• Add pcoa() to compute principal coordinates analysis.

Enhancements

• Allow to display extra qualitative and quantitative variables in viz_rows()/viz_individuals() and viz_columns()/viz_variables().

Bugfixes & changes

• Deprecate hightlight argument of viz_rows()/viz_individuals() and viz_columns()/viz_variables().

dimensio 0.8.1 (2024-07-30)

Internals

• Use palette functions from khroma.

dimensio 0.8.0 (2024-06-07)

Enhancements

• Improve aesthetic mapping in scatterplots.
• Faster computation of non-overlapping labels.

Internals

• Store supplementary variables in a list in MultivariateAnalysis object.

dimensio 0.7.0 (2024-04-09)

Bugfixes & changes

• Fix highlighting in viz_individuals() and viz_row().
• The default number of labeled points can now be changed in viz_individuals(), viz_row(), viz_variables() and viz_columns().

Enhancements

• Allow to highlight supplementary qualitative variables in viz_individuals(), viz_row(), viz_variables() and viz_columns().

dimensio 0.6.0 (2024-02-23)

New classes and methods

• Add predict() method for MCA.

Bugfixes & changes

• By default, viz_individuals(), viz_row(), viz_variables() and viz_columns() only display labels of the 10 observations contributing the most to the factorial map.

Enhancements

• viz_contributions() displays the expected average contribution.
• pca() gained a new argument to specify supplementary qualitative variables.

Breaking changes

• plot_*() methods are now defunct (deprecated in v0.4.0).

dimensio 0.5.0 (2023-11-24)

New classes and methods

• Add cdt() to compute the complete disjunctive table of a factor table.
• Add burt() to compute the Burt table of a factor table.
• Add mca() to compute multiple correspondence analysis.

Enhancements

• biplot() allows to produce a symetric CA biplot.
• Set graphical parameters as arguments in biplot().
• Add automatic legend in biplot().

Internals

• Import arkhe.

dimensio 0.4.1 (2023-10-19)

Bugfixes & changes

• Put ... after required arguments.

Enhancements

• viz_individuals(), viz_row(), viz_variables(), viz_columns() and biplot() gained new arguments allowing set the x and y limits of the plot.

dimensio 0.4.0 (2023-08-23)

New classes and methods

• Add screeplot() to produce a scree plot.
• Add viz_*() methods to replace plot_*() methods.

Bugfixes & changes

• Deprecate plot_*() methods. The internal use of ggplot2 is poorly interoperable or composable. This will reduces hard dependencies.

dimensio 0.3.1 (2023-04-04)

Bugfixes & changes

• Fix rownames() and colnames() for S3 generic/method consistency.

dimensio 0.3.0 (2022-08-15)

New classes and methods

• Add biplot() to produce PCA and CA biplots.
• Add plot_individuals() and plot_variables() methods for PCA class.
• Add tidy() and augment() to get coordinates in tidy format with extra information.
• Add wrap_hull() to compute convex hull around coordinates.
• Add a ggplot2 layer: stat_hull() (thanks to ggplot2 documentation)

Enhancements

• plot_rows and plot_columns() gained new arguments allowing to highlight additional information by varying different graphical elements.
• get_coordinates() gained a new argument allowing to select principal or standard coordinates.

Breaking changes

• Remove plot() methods for PCA and CA classes.
• Remove bootstrap() and jackknife() methods for numeric and integer vectors.

dimensio 0.2.2 (2021-09-18)

New classes and methods

• Add bootstrap() and jackknife() methods for numeric and integer vectors.

Bugfixes & changes

• Fix sign of singular vectors for consistency with FactoMineR.

Internals

• Add BootstrapVector and JackknifeVector classes to store bootstrap and jackknife resampling values (inherit from base numeric).

dimensio 0.2.1 (2021-05-17)

Bugfixes & changes

• Fix row names in build_results(). When initializing a MultivariateResults object with supplementary observations, the row names of the standard and contributions matrices were incorrect (computation moves all supplementary points at the end of the results).

dimensio 0.2.0 (2021-04-22)

New classes and methods

• Add bootstrap() for partial bootstrap analysis.
• Add BootstrapCA and BootstrapPCA: S4 classes to store partial bootstrap analysis.

Bugfixes & changes

• Rename plot_individuals() and plot_variables() to plot_rows() and plot_columns().
• Remove plot_eigenvalues().

dimensio 0.1.0

• Prelease.
