Let's make a tidy table with our baking bots.

.big[.code-green[

```r
# Character vector of baking_bot names
baking_bots <- c("Whiskers", "Baker-waker", "BB-8")
 
# Numeric vector of bot ages
bot_ages <- c(1, 2, NA)
```

# Key terms

<table>
 <thead>
  <tr>
   <th style="text-align:center;"> Term </th>
   <th style="text-align:left;"> Definition </th>
  </tr>
 </thead>
<tbody>
  <tr>
   <td style="text-align:center;"> <code> object   </code> </td>
   <td style="text-align:left;"> A variable in R that we assign different values to using the assignment operator. </td>
  </tr>
  <tr>
   <td style="text-align:center;"> <code> <-   </code> </td>
   <td style="text-align:left;"> The <b>left-arrow</b> or assignment operator can assign a value to a new object or update an existing object. </td>
  </tr>
  <tr>
   <td style="text-align:center;"> <code> package   </code> </td>
   <td style="text-align:left;"> An add-on for R that contains new functions someone created to help you. It's like an App for R. </td>
  </tr>
  <tr>
   <td style="text-align:center;"> <code> library   </code> </td>
   <td style="text-align:left;"> The name of the folder that stores all your packages, and the function used to load a package. </td>
  </tr>
  <tr>
   <td style="text-align:center;"> <code> function   </code> </td>
   <td style="text-align:left;"> Functions perform an operation on your data and returns a result. The function <code>sum()</code> takes a series of values and returns the sum for you. </td>
  </tr>
  <tr>
   <td style="text-align:center;"> <code> argument   </code> </td>
   <td style="text-align:left;"> Arguments are options or inputs we pass to a function to change how it behaves. The argument <code>skip = 1</code> tells the <code>read_csv()</code> function to ignore the first row when reading in a data file. To see the default values for a function you can type <code>?read_csv</code> in the console. </td>
