FactoMineR: An R Package for Multivariate Analysis: Abstract: 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 …

FactoMineR — Multivariate Exploratory Data Analysis and Data Mining. PCA with FactoMineR As you saw in the video, FactoMineR is a very useful package, rich in functionality, that implements a number of dimensionality reduction methods. Its function for doing PCA is PCA() - easy to remember!

2 FactoMineR: An R Package for Multivariate Analysis a partition on the variables; a partition on the individuals; a hierarchy structure on the variables. 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). No need

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. When interpreting the biplot, the greater the perpendicular distance from the axis to the point, the stronger the correlation between the axis and the point. Multiple Correspondence Analysis (MCA) is an extension of simple CA to analyse a data table containing more than two categorical variables. fviz_mca() provides ggplot2-based elegant visualization of MCA outputs from the R functions: MCA [in FactoMineR], acm [in ade4], and expOutput/epMCA [in ExPosition].

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)).

A rich documentation is available on the FactoMineR official website ( http://factominer.free.fr/index.html ) and on youtube. I am trying to extract the principal components for a covariance matrix using PCA in FactoMiner. However, for some reason , I only see n-1 components in the var-->coord variable. library(FactoMineR) x = matrix(rnorm(10000),nrow = 100,ncol = 100) y = PCA(x,ncp = 100,graph = FALSE) dim(y$var$coord) This leads to an output of 100 99.
