Need help in starting R presentation

[Vikram Rawat]

When I search Presentation in R. I see like 10's of ways to do it. 

Like there has been no updates in SLIDIFY package. I think it has been drop dead.

and in basic R presentation, I didn't understand how to use plotly.

and many more.

They all look quite different than one another. Can anybody suggest me which is more promising and how to start it?

I just want to know which of these will be continued and I can use it in production right from now on. Please help me out.
