How to implement hierarchical latent dirichlet allocation in R?
Okay, got it. And how do I preprocess my text data?
Text preprocessing involves several steps such as tokenization, removing stopwords, stemming, and more. You can use the 'tm' package in R to perform these steps. For example, use the 'tm_map' function to remove stopwords and use the 'stemDocument' function to perform stemming.
