trace subsumes browser, it's much more flexible and can be applied to library code without editing it.
- tylermw 2y agotrace is great for shimming in your own code to an existing function, but it’s not an interactive debugging tool.
- disgruntledphd2 2y agoIt sure is. If you set the second argument to browser you can step through any function.
- wdkrnls 2y agoIs there a way to trace an attribute to a function? I couldn't find one, but curious if it exists. I seemed blocked by the fact that trace seemed to expect a name as a character string. Some functions in base R have functions in their attributes which modify their behavior (e.g. selfStart). I ended up just copying the whole code locally and then naming it, but for a better interactive experience I really wish there was a way to pass a function object as I can with debug.
