Exploratory data analysis methods to summarize, visualize and describe datasets. The main principal component methods are available, those with the largest potential in terms of applications: principal component analysis (PCA) when variables are quantitative, correspondence analysis (CA) and multiple correspondence analysis (MCA) when variables are categorical, Multiple Factor Analysis when About FactoMineR .

Performs Multiple Factor Analysis in the sense of Escofier-Pages with supplementary individuals and supplementary groups of variables. Rcmdr Plugin for the 'FactoMineR' package. Details. The function first built a hierarchical tree. Then the sum of the within-cluster inertia are calculated for each partition. The suggested partition is the one with the higher relative loss of inertia (i(clusters n+1)/i(cluster n)).

In conclusion, we described how to perform and interpret principal component analysis (PCA). We computed PCA using the PCA() function [FactoMineR]. Next, we used the factoextra R package to produce ggplot2-based visualization of the PCA results. There are other functions [packages] to compute PCA in R: Using prcomp() [stats]

Finally we wanted to provide a package user friendly and oriented towards the practitioner which is what led us to implement our package in the Rcmdr package (Fox2005).

FactoMineR: An R Package for Multivariate Analysis: Abstract: In this article, we present FactoMineR an R package dedicated to multivariate data analysis.

Performs Multiple Correspondence Analysis (MCA) with supplementary individuals, supplementary quantitative variables and supplementary categorical variables. Performs also Specific Multiple Correspondence Analysis with supplementary categories and supplementary categorical variables. Exploratory Multivariate Analysis By Example Using R. FactoMineR uses the square correlation ratios (which in curvilinear relationships are equal to the eta^2 values) to plot the variables.

The installation, however, is not quite as easy, since the procedure documented on the web site of FactoMineR has alot of problems. Here is a quote of the webbpage: the graph to plot ("ind" for the individuals and the categories, "var" for the variables, "quanti.sup" for the supplementary quantitative variables) Exploratory multivariate analysis with R and FactoMineR - YouTube. This video shows how to perform exploratory multivariate analyses in a French way using R and FactoMineR and how to handle These packages include: FactoMineR, ade4, stats, ca, MASS and ExPosition. However, the result is presented differently according to the used packages. To help in the interpretation and in the visualization of multivariate analysis - such as cluster analysis and dimensionality reduction analysis - we developed an easy-to-use R package named 3/29/2013 FactoMineR, an R package dedicated to multivariate Exploratory Data Analysis.

To help in the interpretation and in the visualization of multivariate analysis - such as cluster analysis and dimensionality reduction analysis - we developed an easy-to-use R package named I am running PCA using FactoMineR and cannot seem to get the individual points labeled on the Individuals factor map. My dataset ("ExData.csv") contains values in a matrix with 13 rows (labeled A through M) and 10 columns (labeled N through W). Thanks for contributing an answer to Stack Overflow!

This method, through an option of the MFA function, allows us to deal Hi, all! I was trying to draw a PCA plot using FactoMineR (a R package). When I ran it, texts on the plots were overlapped with unknown numbers. In this article, we present FactoMineR an R package dedicated to multivariate data analysis. The main features of this package is the possibility to take into account different types of variables (quantitative or categorical), different types of structure on the data (a partition on the variables, a hierarchy on the variables, a partition on the individuals) and finally supplementary R MCA -- FactoMineR. Performs Multiple Correspondence Analysis (MCA) with supplementary individuals, supplementary quantitative variables and supplementary categorical variables.

FactoMineR is an R package dedicated to multivariate Exploratory Data Analysis. It is developed and maintained by François Husson, Julie Josse, Sébastien Lê, d'Agrocampus Rennes, and J. Mazet.
