- [Narrator] Of the many different components … in R marked down document, "code chunks" are … probably the most complex and where you'll spend … most of your time writing. … I've highlighted the two code chunks in the exercise files … that we're going to look at in a minute or two. … How do we know that we're looking at a code chunk exactly … in an R marked down document? … Well, they start and end with three backticks, … and our studio colors them gray, … so that we can easily tell them apart … from the rest of our document … where we're not writing R code. … Code chunks have four components to them. … The first is the "chunk language". … This could be R, Ash, Python, SQL or some other language. … For most R marked down users, the chunk language … will be the R language, because that's what we are, … we're people who write R code. … After the chunk language, we can set … a name for the code chunk. It's highly recommended … that you always name your code chunks, … so it's easier to troubleshoot the knitting process. …
