Halloween Costume Names Text Analysis with Wordcloud in R

In this R tutorial, we will determine the most common Halloween costumes names by using a list of over 5000 Halloween costumes submitted by people.  The costumes will be classified by text analysis and visualize the common names using Wordcloud.

Install and Load Packages

Below are the packages and libraries that we will need to load to complete this tutorial:

Download and Load the Halloween Costume Names Dataset

Since we will be using the Halloween costume names dataset, you will need to download this dataset. This dataset is already packaged and available for an easy download from the dataset page or directly from here Halloween Costume Name Dataset – halloween_costume_names.csv

View the Halloween Costume Names Dataset

head() function

In order to have an idea of what data is being processed, we can use the head() function to view sample data of the costume names and we will print the first 20 rows.

str() function

An alternative way to print sample data is using the str() function. The str() command displays the internal structure of an R object. This function is an alternative to summary(). When using the str() function, only one line for each basic structure will be displayed.

summary() function

Another function to print data from the sms_raw file is using the summary() function. The summary() function is a basic function that issued to produce the result summary of various model functions.

Cleaning the Halloween Costume Names

Below are sample outputs that are used to clean the raw data file for the costumes. A few topics in which are used to clean the file are listed below:

What will be removed from the costume names?

1. remove words/stop words
2. remove white spaces
3. remove punctuation
4. returning words to root form

Build the Halloween Costume Names Wordcloud

Below are the Wordclouds used for the above cleaning of the Halloween costume names. Below are a series of tasks that must be completed to clean and validate the Halloween costume names.

1. transform letters to lowercase
2. remove numbers
3. remove stop words
4. remove all punctuation
5. remove stem words in a text document using Porter’s stemming algorithm.
6. remove white spaces

Now that we have cleaned the Halloween costume name, we can create the Wordcloud for the costume names.

Halloween Costume Names Wordcloud Black and White

Halloween Costume Names Wordcloud Color

There are many colors that can be used with the RColorBrewer package. Below is a picture with a few color combinations to use in the next Wordcloud.

We can create a color variable from one of the color names from the above. For this tutorial, we will use the PuOr color combination.

Hope you enjoyed this tutorial and have some fun changing up the Wordcloud with various sizes and colors.
