Factominer r

The Question is easy. I'd like to biplot the results of PCA(mydata), which I did with FactoMineR. As it seems I can only display ether the variables or the individuals with the built in ploting dev

In order to successfully install the packages provided on R-Forge, you have to switch to the most recent version of R or, alternatively This is a tutorial on how to run a PCA using FactoMineR, and visualize the result using ggplot2. Introduction Principal component analysis (PCA) is a statistical procedure that uses an orthogonal transformation to convert a set of observations of possibly correlated variables into a set of values of linearly uncorrelated variables called principal components ( Wikipedia ). 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 finally supplementary Cannot retrieve contributors at this time. 741 lines (717 sloc) 55.7 KB Raw Blame I am running the following: mydata <- read.csv ("ExData.csv",header=TRUE,row.names=1) attach (mydata) library (FactoMineR) X <- cbind (N,O,P,Q,R,S,T,U,V,W) res.pca <- PCA (X) When PCA runs, I get the Individuals factor map (PCA) with the points labeled 1-13, instead of A trough M.

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)).

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. 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.

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.
