title: Extracting Principal Components in FactoMiner R
body: <p>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</p>
  
  <pre><code>library(FactoMineR)
  x = matrix(rnorm(10000),nrow = 100,ncol = 100)
  y = PCA(x,ncp = 100,graph = FALSE)
  dim(y$var$coord)
  </code></pre>
  
  <p>This leads to an output of 100 99. I am new to this package and hope to get more insights</p>
