The goal of the YesSiR package is to generate automatic reports based on the FactoMineR and officer packages. Reports are issued from multivariate analyses such as MCA and PCA. To use the package you have to use the .pptx file included in the package.
You can install the released version of YesSiR from GitHub with:
# install.packages("devtools")
devtools::install_github("Sebastien-Le/YesSiR")
