usdatasets: A Comprehensive Collection of U.S. Datasets • usdatasets

Introduction

The usdatasets package provides a comprehensive collection of U.S. datasets, encompassing various fields such as crime, economics, education, finance, energy, healthcare, and more. This package serves as a valuable resource for researchers and analysts seeking to perform in-depth analyses and derive insights from U.S.-specific data.

Dataset Suffixes

To facilitate the identification of data types, a suffix is added to the end of the name of each dataset. These suffixes indicate the format and type of the datasets, such as:

tbl_df: A tibble data frame
df: A standard data frame
ts: A time series object
matrix: A matrix object
character: A character vector
numeric: A numeric vector
factor: A factor variable

Example Datasets

Here are some examples of datasets included in the usdatasets package:

marathon_tbl_df: A tibble containing marathon race data, including runner statistics and performance metrics.
mn_police_use_of_force_df: A data frame documenting incidents of police use of force in Minnesota.
nba_players_19_tbl_df: A tibble that includes data on NBA players for the 2019 season.
ncbirths_tbl_df: A tibble summarizing birth statistics across various demographics.
nyc_marathon_tbl_df: A tibble containing results and statistics from the New York City Marathon.
nycvehiclethefts_tbl_df: A data frame documenting vehicle theft incidents in New York City.

Visualizing Data with ggplot2

To illustrate the data, we can use the ggplot2 package to create some visualizations. Here are a few examples:

1. Visualization of Marathon Finish Times


# Example: Visualizing finish times of the NYC Marathon
# Ajustado para las columnas disponibles en 'marathon_tbl_df'
marathon_tbl_df %>%
  ggplot(aes(x = year, y = time, color = gender)) +
  geom_point(alpha = 0.6) +
  labs(title = "Marathon Finish Times by Year and Gender",
       x = "Year",
       y = "Finish Time (minutes)",
       color = "Gender") +
  theme_minimal()

2. Visualization of NBA Player Heights


# Example: Visualizing the distribution of NBA player heights
nba_players_19_tbl_df %>%
  ggplot(aes(x = height)) +
  geom_histogram(binwidth = 2, alpha = 0.7, fill = "blue", color = "black") +
  labs(title = "Distribution of NBA Player Heights",
       x = "Height (inches)",
       y = "Count") +
  theme_minimal()

3. Visualization of Police Use of Force Incidents


# Example: Visualizing police use of force incidents by race
mn_police_use_of_force_df %>%
  group_by(race) %>%
  summarize(count = n()) %>%
  ggplot(aes(x = reorder(race, count), y = count, fill = race)) +
  geom_bar(stat = "identity") +
  labs(title = "Incidents of Police Use of Force by Race",
       x = "Race",
       y = "Number of Incidents") +
  theme_minimal() +
  coord_flip()

Conclusion

The usdatasets package is an invaluable tool for those looking to analyze and derive insights from a variety of U.S.-specific datasets. The suffixes used in the dataset names help users quickly identify the type of data they are working with, facilitating a smoother analysis process.
