Background

Using the janeaustenr package, I will filter for the book “Emma”, I will be counting the number of words, and plotting the frequency of the most common words in bar chart using ggplot2. I will also remove stop words using the tidytext, stop_words() function.

# Filtering for "Emma" specifically from the package "janeaustenr"
emma_book <- austen_books() %>%
    filter(book == "Emma") %>%  
    mutate(line = row_number())  


# breaking text into words
emma_tidied <- emma_book %>%
    unnest_tokens(word, text)  


# removing stop words using tidytext::stop_words
emma_filtered <- emma_tidied %>%
    anti_join(tidytext::stop_words, by = "word")  

# counting frequency of most common words used in the book in descending order
emma_word_count <- emma_filtered %>%
    count(word, sort = TRUE)  

# extracting the top 15 most frequently occurring words for visualization.
emma_top_words <- emma_word_count[1:15, ]

# Create the plot
graph_exercise1 <- ggplot(emma_top_words, aes(x = reorder(word, n), y = n)) +
    geom_col(fill = "pink") +  
    coord_flip() + 
    labs(
        title = "Top 15 Common Words in 'Emma' by Jane Austen",
        x = "Words",
        y = "Frequency"
    ) +
    theme_minimal()
