Extend ur_scrape_arwu() to scrape 501-1000
Currently, the ur_scrape_arwu()
function scrapes the Top 500 ranked universities. Following code run to verify this:
> # retrieve 2018 rankings
> arwu_ranks_2018 <- ur_scrape_arwu(2018)
>
> # count rows
> nrow(arwu_ranks_2018)
[1] 500
Could we have this scraper modified to optionally scrape the 501-1000 ranked universities?
