plot() function - basic parameters (2)
You can add even more customization with the plot() function using other options. As you saw in the video, the lines() function is especially helpful when you want to modify an existing plot.
Let's look at another example:
> # Use bars instead of points and add subtitle
> plot(mydata, type = "h", sub = "Subtitle")
> # Triple thickness of line and change color to red
> lines(mydata, col = "red", lwd = 3)
In this exercise, you will try some of this customization for yourself. The same dataset, data, is available in your workspace. (If you can't remember the names of the columns, run colnames(data) in your console.)
