  .progress = FALSE
)

Arguments

urls_to_expand	character vector of URLs
warn	show any warnings (API or otherwise) as messages
agent	user agent to use (some sites switchup content based on user agents). Defaults to "'longurl-r-package'".
seconds	number of seconds to wait for a response until giving up. Cannot be <1ms.

big_urls <- expand_urls(test_urls)
head(big_urls)

Tools expand vectors of short URLs into long URLs

Description

Tools are provided to expand vectors of short URLs into long 'URLs'. No 'API' services are used, which may mean that this operates more slowly than 'API' services do (since they usually cache results of expansions that every user of the service requests). You can setup your own caching layer with the 'memoise' package if you wish to have a speedup during single sessions or add larger dependencies, such as 'Redis', to gain a longer-term performance boost at the expense of added complexity.
