[Solved] How to add zoom option for wordcloud in Shiny (with reproducible example)

Question

Normalisation is required only if the predictors are not meant to be comparable on the original scaling. There’s no rule that says you must normalize.

PCA is a statistical method that gives you a new linear transformation. By itself, it loses nothing. All it does is to give you new principal components.

You lose information only if you choose a subset of those principal components.
