NJ Spotlight ran a story, "What Would ‘Full Funding’ of School Aid Look Like? Add $2.3B to Districts", and made the data public. I can't download the whole thing in one go, and I don't feel like clicking through 24 pages and copy+pasting each one into a spreadsheet, so scrape I shall!
This dataset includes capped SFRA aid, including adjustment aid, for 2018-19 school year as well as actual state aid recieved in 2017-18. However, NJ Spotlight also obtained uncapped SFRA aid without adjustment aid. It doesn't seem like this variable is made publicly available by the State. Ideally, I'd like to also have adjustment aid as a separate variable.
The full dataset is in the data/ folder. It contains funding scenarios for all(?) school districts in NJ.
If you want to copy me, just run all lines of R/compile_data.R. See "Requirements" below for dependencies.
This website is dynamically generated ("Javascript is modifying the state of the DOM"), so rvest's functions cannot extract the data. rdom takes care of this.
The catch: It seems like rvest and xml2 have no functions capable of dealing with the output of rdom's functions. XML::readHTMLTable(), however, does the job.
For rdom to work, you must have phantomjs.exe in the working directory. You can download it here. You only need to move the phantomjs.exe file into your working directory. I used v2.1.1, the last stable version that will ever(?) be released (RIP).
Alternatively, you can probably download PhantomJS using the wdman package.
