get_urls_kj: Scrape Kijiji listing URLs
In UPGo-McGill/upgo: Utility Functions for UPGo Lab Members

get_urls_kj scrapes Kijiji listing URLs for a city.

get_urls_kj(
  city_name,
  short_long = "both",
  timeout = 1,
  proxies = NULL,
  quiet = FALSE
)

`city_name`	A character string: the city to be scraped.
`short_long`	A character string, either "short" or "long" or "both", to determine whether STR or LTR listing URLs should be scraped.
`proxies`	Character vector of IPs to use for proxy connections. If the length is less than the number of processes set by 'future::plan()', proxies will be recycled.
`quiet`	A logical vector. Should the function execute quietly, or should it return status updates throughout the function (default)?
