The report include the:

  • detection of existing outliers,
  • identification of the major first principal components,
  • plots,
  • description of dimensions

Install and load Required packages

Demo examples

# Load Packages
library("FactoMineR")
library("FactoInvestigate")
# Principal component analyses
data(decathlon)
res.pca <- PCA(decathlon, quanti.sup = 11:12, quali.sup = 13, graph = FALSE)
Investigate(res.pca, file = "PCA.Rmd", document = "pdf_document", 
            parallel = TRUE)
# Correpondance analysis
data(children)
res.ca = CA(children, row.sup = 15:18, col.sup = 6:8, graph = FALSE)
Investigate(res.ca, file = "CA.Rmd", document = "html_document")
# Multiple correspondance analysis
data(tea)
res.mca = MCA(tea, quanti.sup = 19,quali.sup = 20:36, graph = FALSE)
Investigate(res.mca, file = "MCA.Rmd", document = c("word_document", "pdf_document"))

The output looks like this:
