Selecting elements from a list

Your list will often be built out of numerous elements and components. Therefore, getting a single element, multiple elements, or a component out of it is not always straightforward.

One way to select a component is using the numbered position of that component. For example, to "grab" the first component of shining$\_$list you type

shining$\_$list$[[1]]$

A quick way to check this out is typing it in the console. Important to remember: to select elements from vectors, you use single square brackets: $[].$ Don't mix them up$!$

You can also refer to the names of the components, with $[[]]$ or with the $ sign. Both will select the data frame representing the reviews:

shining$\_$list$[["$reviews$"]]$

shining$\_$list$reviews

Besides selecting components, you often need to select specific elements out of these components. For example, with shining$\_$list$[[2]][1]$ you select from the second component, actors $($shining$\_$list$[[2]]),$ the first element $([1]).$ When you type this in the console, you will see the answer is Jack Nicholson.
