# logrx Options

One of the ways that `logrx` has been built to be customizable is to add a set of options to enable different logging and execution elements.

Below are the options and their default values

option | value | description
--- | --- | ---
log.rx | An empty R environment | Used to store log elements during program exection
log.rx.exec.env | NULL | The environment in which the program code is executed
log.rx.lint | FALSE | A `lintr` object for use in lint checking
log.rx.approved | ./approved.rds | Location of an approved functions file

## log.rx.lint

“lintr provides static code analysis for R. It checks for adherence to a given style, identifying syntax errors and possible semantic issues, then reports them to you so you can take action.”

Linting can help enforce best practice for a variety of topics including code readability, efficiency, style, consistency, etc. You can find all available linters here, or create your own.

If you or your organization would like to implement any linters, you can set your `log.rx.lint` option globally so your specific set of checks are run and their results are recorded to your log for every script executed.

It is recommended to use the `library_call_linter()`. This is to ensure `logrx` will find the correct package and functions used.
