Imputing sales data

You've been asked to create a report that allows management to compare sales figures per quarter for two years. The problem is that the dataset (sales_df) contains missing values. You'll need to impute the values in the year column so that you can visualize the data.

The ggplot2 package has been pre-loaded for you.
