dimensio 0.3.0

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

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

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

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.
