title: How can I make R's output more verbose so as to reassure me that it hasn't broken yet?
body: <p>I often run code that eats up a lot of RAM, and may take as much as an hour before it gives its outputs. Often, I'll be half an hour in to running such code and I'll be worrying that something gone wrong. Is there any way that I can get R to reassure me that there's not been any errors yet? I suppose that I could put milestones in to the code itself, but I'm wondering if there's anything in R (or RStudio) that can automatically do this job at run time. For example, it would be handy to see how much memory the code is using, because then I'd be reassured that it's still working whenever I see the memory use significantly vary.</p>
