Welcome to the community, Mariam! 
I'm afraid you're unlikely to get this type of help here. There are lots of materials available for R, not just the cloud tutorials by RStudio. I'll paste links of some online books for beginners below, but you'll have to go through those yourself.

There are other options though. There is a package swirl, which certainly helps you to learn R interactively. You can try that:

And, there's a Slack community, but that's specifically for following a particular book R4DS. That's a very popular book, at least among people who wants to learn tidyverse (a group of R packages). You can find that here:

Hope this helps.
