searcher v0.0.2 Released

The searcher provides a search interface to look up terms on popular websites such as ‘Google’, ‘Bing’, ‘DuckDuckGo’, ‘StackOverflow’, ‘GitHub’, and ‘BitBucket’. Upon calling a searcher functions, a browser window will open with the search results for the query.

Example searcher usage

The idea for searcher began as a project to automatically search errors and warnings that occurred while working with R after a conversation among Dirk Eddelbuettel, Barry Rowlingson, and myself. However, there was no search interface that allowed querying directly from R outside of the built-in utils::RSiteSearch(), which only queries, and the sos package, which queries an off-site user premade database. Both of these options were focused solely on querying R documentation made available by packages. Given the nature of errors generally being undocumented, neither of these approaches could be used. Thus, searcher was unintentionally born to provide a means for errorist, which contains a robust way to automatically searching errors and warnings.
