<p>	<span>debugr </span>is a new package designed to support debugging in R. It mainly provides the <span>dwatch()</span> function which prints a debug output to the console or to a file. A debug output can consist of a static text message, the values of one or more objects (potentially transformed by applying some functions) or the value of one or multiple (more complex) R expressions. Whether or not a debug message is displayed can be made dependent on the evaluation of a criterion phrased as an R expression. Generally, debug messages are only shown if the debug mode is activated. The debug mode is activated and deactivated with <span>debugr_switchOn()</span> and <span>debugr_switchOff()</span>, respectively, which change the logical <span>debugr.active</span> value in the global options. Since debug messages are only displayed in debug mode, the <span>dwatch()</span> function calls can even remain in the original code as they remain silent and won’t have any effect until the debug mode is switched on again. <b>Read more</b>: </p>
