Error with connecting R to AWS

[aureliuszi]

Describe the bug
Documentation (as it is) does not account for how to open AWS S3 in R.

To Reproduce
Several new users (including Zi, on a new laptop) cannot get AWS S3 to list buckets in R, despite being able to do so on previous computer.

Expected behavior
We expect the R console to interact with AWS but it doesn't.

Screenshots
We get error 127 when we try.

Desktop (please complete the following information):

• OS: Windows
• Version R4.1.2
