# Rendering

So far we've used the RStudio button to 🧶

What about on the command line?

# Your turn

Instead of using the "Knit" button, try running this code in your R console:

```r
library(rmarkdown) # needs to be loaded first
render("01-bakeoff-report.Rmd")

# or

rmarkdown::render("01-bakeoff-report.Rmd")
```

Now try changing the parameters:

```r
render("01-bakeoff-report.Rmd",
       params = list(series = "9"))
```

__If this was easy__, play with the other parameters too. Or see if you can change the output format, and add output option `toc = TRUE`.

???
The rendered document doesn't appear in a pop up and you will have to click on the newly created `01-bakeoff-report.html` which corresponds to the `.rmd` file.

A hint for finding the parameters to a function is to select F1 when the cursor is in the word `render`.

The help files will appear in the bottom right panel of RStudio.

# Take-aways

✔️ **Documents run sequentially** the order of your code chunks matters

✔️ **Click or code** the flexibility of RMarkdown is that you can use RStudio or code in the console

❗ **RMarkdowns are self-contained** any data use needs to be coded in the script and not "pre-loaded" in RStudio

❗ **Manual parameters overwrite the output** each output needs to be saved individually - this can be laborious
