Benjamin Smith creates a function:

While it is possible to use the paste() or paste0() for string concatenation. I do understand how it can be messy to deal with, especially when working with loops and/or nested functions. In this short blog I share a remedy for this by writing a special function which can lend for cleaner code as opposed to using paste() or paste0().

It’s not quite as nice as a here string (e.g., @"{FirstName} just referenced the name here string at {UserTime}" user.FirstName DateTime.UtcNow) but this is a good reminder that operator creation in R is pretty easy. H/T R-Bloggers.

Bryan Shalloway continues looking at Twitter data:

This is a follow-up to a short post I wrote on R Access to Twitter’s v2 API. In this post I’ll walk through a few more examples of pulling data from twitter using a mix of Twitter’s v2 API as well as the {rtweet} package.

I’ll pull all Twitter users that I (brshallo) have recently been engaged by (e.g. they like my tweet) or engaged with (e.g. I like their tweet). I’ll lean towards using {rtweet} but will use {httr} in cases where it’s more convenient to use Twitter’s v2 API.

Bryan Shalloway dives into the mess known as Twitter:

academictwitteR is probably the most established package that provides a quickstart entry point to the V2 API. However it requires creating an academic account in twitter, i.e. the user must be affiliated with a university. I also stumbled onto RTwitterV2 and voson.tcn which both also provide quickstarts on the V2 API, but did not explore these.

Instead I followed the tutorial Getting started with R and v2 of the Twitter API by Twitter Developer Advocate Jessica Garson that uses {httr} to interact more directly with the API. I highly recommend reading her tutorial. The code below is mostly just copied from there but changed to provide an example of getting the usernames of those that liked a tweet.
