First block of example code

The first line of the code block should read "tidy_tweet <- tweets %>%"

The way it is currently written references "tidy_tweet" before it has been created.

Note from the Author or Editor:
Many thanks to this careful reader! The first line of the first code block on page 121 of the print version should read:

tidy_tweets <- tweet %>%

Instead of what it current reads:

tidy_tweet %>%
