-Description: Duct tape the 'quanteda' ecosystem (Benoit et al., 2018) <doi:10.21105/joss.00774> to modern Transformer-based text classification models (Wolf et al., 2020) <doi:10.18653/v1/2020.emnlp-demos.6>, in order to facilitate supervised machine learning for textual data. This package mimics the behaviors of 'quanteda.textmodels' and provides a function to setup the 'Python' environment to use the pretrained models from 'Hugging Face' <https://huggingface.co/>.

 [^caret]: The function `confusionMatrix()` can accept the predicted values and ground truth directly, without using `table()` first. But the predicted values and ground truth must be `factor`: `confusionMatrix(as.factor(predicted_sentiment), as.factor(docvars(test_corpus, "value")), mode = "prec_recall")`.
