The environment browser invoked by browser() is the same one used in all of the other debugging facilities, so it can be considered the lowest-level debugging tool.

Unlike an editor breakpoint, the browser() statement is actually part of your code, so it needs to be applied like any other code change in order to become active (by sourcing the containing document, rebuilding the containing package, reloading the Shiny application, etc.). Right-click any item or space on a web page, then select Inspect Element.

To install and use via the command-line, you. Here, for instance, it’s used to halt when a function is about to return TRUE: Below is a brief description of the install methods, and then I’ll explain an even better method to get it to run on any website, remote or local. You can put browser() anywhere in your code to stop at that point in the code for debugging. The R function browser() halts execution and invokes an environment browser when it is called. In most cases, you can source() the file to resolve the problem. The circle outline indicates that RStudio is aware of the breakpoint, but that it hasn’t been injected. Then I select Body Text in the 'Outline level' drop-down, and 'Collapsed by default' stays un-checked and goes back to grey. If the function object doesn’t exist yet (for instance, because you haven’t called source() on the file), or the function object doesn’t match the contents of the editor (for instance, because you’ve changed the file since the last source()), the breakpoint will be deferred. However, if I select anything else in the 'Outline level' drop-down, then 'Collapsed by default' will be active again, and I can de-select it. R function objects that include this tracing code have a red dot in the environment pane, indicating that they contain breakpoints. Editor breakpoints take effect immediately and don’t require you to change your code (unlike browser() breakpoints, below).Įditor breakpoints work by injecting some tracing code into the R function object. You can do this in RStudio by clicking to the left of the line number in the editor, or by pressing Shift+F9 with your cursor on the desired line. I can still open and edit scripts like normal, its just that the titles appear grayed out. The script in the picture is an empty script added to a newly created empty project. The most common (and easiest) way to stop on a line of code is to set a breakpoint on that line. Script Names/Titles Appear Grayed out in Inspector Question Whenever I add a new script to a project the title always appears greyed out, here's a pic to demonstrate.
