ggfacto 0.4.0 (2026-09-22)

One workflow for the three analyses: the analysis, interpret() for its axes, ggfacto() for its graph, hierarchical_clust() for its clusters. See the guide: https://bricenocenti.github.io/ggfacto/articles/ggfacto.html.

New functions

• multiple_correspondence_analysis(), principal_component_analysis(), correspondence_analysis() (from a tabxplor::tab()): the analyses, weights and variables selected as in tab().
• interpret(): the table of an analysis' axes, with its eigenvalues below; eigenvalues() alone.
• ggfacto(): the graph of any of the three analyses; ggpca(), the individuals of a PCA and its biplot.
• hierarchical_clust(): HCPC()'s clusters, in linear memory, written into the data with mutate(); clust_tab() describes them.
• axis_coord(), is_in_analysis(): an analysis' coordinates, and its population, back into the data. name_axes() names the axes on graphs and tables.

New arguments and changes

• excl = takes exact level names; missing answers become <VAR>.NA levels, excluded by default (specific MCA).
• filter = analyses a subset; the whole data frame is then passed to every later function.
• clust =, names =, interactive =, lang =; options(ggfacto.widget_dir) writes widgets to their own file in documents.
• profiles = TRUE and active_tables = "active" are the defaults: the crosstables of the Burt table are in the tooltips.
• The MCA is fitted on the distinct answer profiles (same results, much faster); MCA2() keeps the 0.3.2 fit on individuals.
• A missing value of a PCA sits at its variable's weighted mean.
• Requires R >= 4.3, ggplot2 >= 4.0 and tabxplor >= 2.0.1.

Deprecations and removals

• HCPC_tab() (use clust_tab()), the cah and dat arguments (use clust and data), and %>% are soft-deprecated.
• pers_or_plot() is removed; ggi(iframe =, pixel_width =) are ignored.

Bug corrections

• The Frequency line of a tooltip could exceed 100 %.
• A question with levels y/n disappeared from the graphs and tables.
• The ellipses of a weighted analysis ignored the weights.

ggfacto 0.3.2 (2024-10-02)

Bug correction

• Corrected to work with dependency package tabxplor:: version 1.2.1

ggfacto 0.3.1 (2024-08-30)

Bug correction

• HCPC_tab() was not working well with numeric variables.

ggfacto 0.3.0 (2024-03-08)

Added :

• New fonction : HCPC_tab()
• New fonction : ggmca_initial_dims()
• New fonction : ggmca_with_base_ref()
• New fonction : ggmca_3d()
• New fonction : PCA2()
• New fonction : pca_interpret()
• New fonction : ggpca_cor_circle()
• New fonction : ggpca_3d()
• New fonction : mean_sd_tab()

Bug correction

• ggmca() can now properly color profiles of answer with cah (HCPC clusters) levels.

ggfacto 0.2.3 (2024-01-25)

Added :

• New argument reverse_axes in ggmca() to invert left and right or up and down.

Bug correction

• mca_interpret was not working with MCA(excl = )
• in ggmca, profiles of answers were plain wrong (because of the unanticipated results of a change in code)

ggfacto 0.2.2 (2021-10-22)

• First public version of ggfacto.
