I love R and dplyr. It is very readable and easy to explain to non-programmers. I use it almost everyday. Not exactly on the topic,I am having difficulties debugging it. May be I need to brush up on debugging R. Not sure if there is a easy way to add breakpoint when using vscode.

browser() ?

  trace subsumes browser, it's much more flexible and can be applied to library code without editing it.

    trace is great for shimming in your own code to an existing function, but it’s not an interactive debugging tool.

      It sure is. If you set the second argument to browser you can step through any function.

    Is 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.
