In this French tutorial, the presenter walks through the Factoshiny package – a Shiny‑based graphical front‑end for the FactoMineR suite. After loading Factoshiny in RStudio, the wine dataset (included in FactoMineR) is used as a demo. The video shows how a single function, Factoshiny(), can be applied to three kinds of objects (raw data, a previous analysis result such as a PCA, or an existing Factoshiny object) and launches a web interface split into a left‑hand description panel and a right‑hand method panel. The left panel lists dataset characteristics, available methods (variable‑characterisation, factorial analyses, classification) and links to instructional videos. Selecting a method (e.g., PCA) opens a second window with a left‑hand configuration menu and a right‑hand results area. The presenter highlights key configuration tabs: choosing active vs. supplementary quantitative/qualitative variables, designating supplementary individuals, handling missing values, improving graph readability, performing post‑PCA classification, generating an automatic bilingual report, and exporting the underlying R code to reproduce the exact plots. All changes are reflected instantly in the graphics, and the session can be saved and later restored simply by re‑running Factoshiny(). The tutorial concludes by encouraging viewers to explore the various functionalities across methods.
