Viewing sports trends

Now that you've manipulated and subsetted your sports data in a number of ways, it's time to step back and consider some trends in the data. The plot on the right shows the cumulative win/loss averages of the Boston Red Sox in the 2015 MLB season and the Boston Bruins in the 2015-2016 NHL season.

Which team had the highest win/loss average at the end of their respective season?

Two xts objects, redsox_2015 and bruins_2015 are available in your workspace. These objects contain the dates of each game played in each season, along with the cumulative win/loss average as of each game (stored in the win_loss column of each object). You can explore these objects using commands such as summary(), structure(), periodicity(), head(), or tail(), or by subsetting.

It is impossible to tell which team had a higher average because the seasons are not temporally aligned.
