21.34 Word Length Counts

A simple plot is then effective in showing the distribution of the word lengths. Here we create a single column data frame that is passed on to ggplot2::ggplot() to generate a histogram, with a vertical line to show the mean length of words.

data.frame(nletters=nchar(words))                                     %>%
  ggplot(aes(x=nletters))                                              + 
  geom_histogram(binwidth=1)                                           +
  geom_vline(xintercept=mean(nchar(words)), 
             colour="green", size=1, alpha=.5)                         + 
  labs(x="Number of Letters", y="Number of Words")
