This series of 21 very short videos is ideal for getting through the first steps of using R. It starts at very basic level. It is best to follow along running the examples in your own computer. You can watch the whole series below, or choose the individual videos from the intro to R list at Google Developers (YouTube).
Please, note that the videos have captions, and that Google provides translation of captions.
One more thing, we will use RStudio, which has a visually different user interface. However, everything in the videos that concerns R itself, will work exactly in the same way on any operating system and editor you use.
