Tomaz Kastrun ends the advent of Azure ML on a downer:
R language and Azure Machine Learning SDK for R was deprecated a year ago (end of 2021). But R can be still used for training and deployment by using Azure Machine learning CLI 2.0!
Furthermore, R language can be used in Machine Learning Designer, for data preparation, data wrangling and statistical analysis.
You can work with R but they make sure everything is more difficult.
