The goal of searcher is to provide a search interface directly inside of R. For example, within R, there is now the ability to look up rcpp example numeric vector or ggplot2 fix axis labels without having to open a browser, go to a search site, and type the query. By default, the search functions automatically search the last error on call. The search_*() functions can be used to search a query directly from R on major search engines, code repositories, and help websites. The following search platforms are supported: Google, Bing, ixquick, DuckDuckGo, StackOverflow, GitHub, and BitBucket. By default, an appropriate suffix for each platform that ensures relevant results to R is appended to all queries. This behavior can be disabled by using rlang = FALSE.
