My name is Phani. I want to choose which is the best model i.e Latent Dirichlet Allocation, Latent Semantic Analysis and Correlated Topic Model for my data. I already preprocessed the data but I want any specific packages in r to run those models and compare the models based on coherence score for my data. So plz suggest any packages or any code to run those models. Thank you.

I already tried in r but it showing error like coherence function is not found. So plz suggest any packages or any code to run those models.
