 Sometimes when you're working in our studio, you may run into a situation where you need to add a code block to a worksheet. In this case here in Rehearse 2 of Lab 6, we only have one empty code block up here for CodeChunk 3. And in the instructions on the website, it appears that you need another code block. What do you do? Well, you can always add code blocks to our markdown pages very simply. I'm going to put my cursor here to a place that I want to add additional code block. I go up to the plus C, insert a new code chunk, click on the down arrow, and then select I want an R code chunk, which it tells me. And there's my empty code block so I could paste in, copy and paste in the libraries that it had on the top, and then a place for additional code to run like that. You can do this anytime you think you need to run code, or if you want to just test some code out. Put in another code block, test out the code, and then if you like it, you can reuse it. If not, you can just delete it, highlight, delete. So that's all there is to it, to insert plus C, R, and then to delete just to highlight and delete. I hope this helps.
