I think it is the awesome feature that has introduced in R.
I really enjoyed this topic.
Also i would like to bring to your kind notice that, till now i have completed learning 12 topics of R.
Contents are synchronized very well.
My question is how much least time is needed to learn & practice R completely considering as a quick learner??
R Data-types-and-Factors 14-15 min 0-10 sec
We are happy to know that you have liked the content. As far as the matter of practicing is concerned, you should build some projects using R. That would help you remember the syntax and applying this language to real-life problems.
