Overview

About

Maintained by Brice NocentiCRAN page ↗GitHub ↗Website ↗Issues ↗

Readable, complete and pretty graphs for multiple correspondence analysis, correspondence analysis and principal component analysis made with 'FactoMineR'. They can be rendered as interactive 'HTML' plots, showing useful information at mouse hover. The interest is not mainly visual but statistical. It helps the reader to keep in mind the data contained in the cross-table or Burt table while reading the correspondence analysis, thus preventing over-interpretation. Most graphs are made with 'ggplot2', which means that you can use the + syntax to manually add as many graphical pieces you want, or change theme elements. 3D graphs are made with 'plotly'.

Changes in 0.4.0

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.

Show all changes in 0.4.0Hide the rest of the changes in 0.4.0

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.

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("ggfacto", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("BriceNocenti/ggfacto")

Development version from BriceNocenti/ggfacto. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-ggfacto

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-ggfacto

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-ggfacto

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
