update 6c for academictwitteR v0.2, don't use positional arguments

[chainsawriot]

Problem

In the recent academictwitteR update (now on CRAN), the package follows the current httr best practices on storing the bearer token. Although hard-coding bearer token still works in academictwitteR, it is no longer recommended. As this is educational material, we also recommend Twitter to educate the API users to follow these best practices. Thus, users don't hard-code their bearer token in their R scripts or burn in their command history.

Also, the usage of positional arguments should be avoided. It is quick, but it can also be confusing from a pedagogical standpoint.

Solution

Using set_bearer() instead of hard-coding. Using very explicit named arguments.

Result

Potentially higher in pedagogical value.
