Among other applications, this can be useful for testing out code locally

+## Disabling the use of environment variables
+
+As mentioned above, it is possible to make use of environment variables to
+configure access. However, if you wish to pass in connection details via a URI
+or alternative methods but also have existing AWS environment variables
defined,
+these may interfere with your session. You can unset these environment
+variables using `Sys.unsetenv()`, for example:
+
+```{r, eval = FALSE}
+Sys.unsetenv("AWS_DEFAULT_REGION")
+Sys.unsetenv("AWS_S3_ENDPOINT")
Review comment:
Should this instead be a snippet which contains instructions for
unsetting env vars and then resetting at end of session?
