Well, it's a different question from the initial one. I would rather recommend you take a look at a few resources first:
- course videos form the creators of the package: FactoMineR: MOOC
- short tutorials (you can google to find more): FactoMineR and factoextra : Principal Component Analysis Visualization - R software and data mining - Easy Guides - Wiki - STHDA
You can also us data sets that come with the FactoMineR package, here's how you can find the list.
data(package = "FactoMineR")
If you need help with your specific case, I would recommend you post a new question with the data and code that you're using, here's how:
Good luck with the topic.
