Join Mark Niemann-Ross for an in-depth discussion in this video Exploring isthisacroppedversionofthat.R, part of Code Clinic: R (2015).
- So, I'm going to go up here and click.…We're in the source window, and I'm clicking on the tab…that says isthisacroppedversionofthat.…And that will show us the code…that we're actually gonna step through.…Let's give it a little bit more room,…and I'll do that by dragging this pane over to the right.…And, what I'd like to do is actually go into the browser.…We'll do a debug version of this thing…to find out what this is happening.…And, we can take a look at some of the values…as we step through.…So, what I'm going to do is in this case,…I could either set up the word browser, just by doing this.…
