how to select among hundreds of R packages??

I had a similar question. Looking for a short answer to how to get the right download from the list of non 64-bit options which will work on my 2017 Mac OS laptop, and then to 'get started' by, say, getting a snippet of code to draw a plot of some probability distribution/s?

Just trying to get started. My one and only other question didn't attract any responses from the community! List of old versions of Rstudio: too many for me easily to determine the latest one for my system

Yours, Ria
