Hi! I´m doing PCA with FactoMineR. I need to obtain a graphic representation of my observations, with different colours to differentiate them.
How can I do this? Tanks!!

Hello @Ana20,
Happy to help you with this if you can provide some data/code. Even better if you can provide a reprex 
(See here: FAQ: How to do a minimal reproducible example ( reprex ) for beginners)
Hello! How can I provide some data? I could not do a reprex, because an error occurred...
You can copy paste data with something like datapasta: https://cran.r-project.org/web/packages/datapasta/vignettes/how-to-datapasta.html
This link should also be able to help you with visualisations for PCA: http://www.sthda.com/english/wiki/wiki.php?id_contents=7851&fbclid=IwAR01E5XVvCrSKnpkCdAppbpvv7YMGvxSWaSSwb4SIgrXjrxoIpMIlNblYFY
