Nicely done! Now, we can create a data frame called quarter_prices whose columns are these two vectors. To do so, we'll use the data.frame() function, like this:
quarter_prices <- data.frame(period, avg_price)
When we run this line of code, R will create a data frame that looks like this:
| period | avg_price | |
|---|---|---|
| 1 | Q1 2017 | 170195 |
| 2 | Q2 2017 | 173937 |
| 3 | Q3 2017 | 177938 |
The data.frame() function takes vector arguments that represent the columns of the data frame you wish to create. In this case, our column vectors are period and avg_price. We then told R to store this data frame object in a column named quarter_prices.
Create a data frame named houses from two vectors that we've already defined for you: ad_code and price (in that order). How many rows are in this newly created data frame?
