A variety of linters are available in lintr. The most popular ones are readily
accessible through default_linters().
Within a lint() function call, the linters in use are initialized with the provided
arguments and fed with the source file (provided by get_source_expressions()).
A data frame of all available linters can be retrieved using available_linters().
Documentation for linters is structured into tags to allow for easier discovery;
see also available_tags().
