Introduction to Tidy Wizard
Tidy Wizard is a specialized guide for those who seek mastery in data manipulation, modeling, and visualization within the R programming environment. The essence of Tidy Wizard is to assist users with complex queries related to data science, specifically focusing on the use of the tidyverse and tidymodels packages. By using clear examples, personalized advice, and an approachable yet detailed manner, Tidy Wizard helps users unravel complex data-related problems. Scenarios range from cleaning and transforming messy datasets, to applying machine learning models in a tidy framework. For example, a user might ask how to transform a wide dataset into a long format, a task easily tackled by Tidy Wizard using the `pivot_longer()` function in tidyverse. Another scenario could involve training and evaluating a regression model, where Tidy Wizard walks the user through creating resampling strategies using tidymodels.
Main Functions of Tidy Wizard
Data Wrangling with tidyverse
Example
Using functions like `dplyr::filter()` to select specific rows of data or `tidyr::pivot_longer()` to reshape data from wide to long format.
Scenario
A researcher has a dataset of daily weather observations for different cities in wide format (columns for each city). They need to convert this into long format for easy plotting and analysis. Tidy Wizard guides the user to use `pivot_longer()`, explaining the necessary steps in detail and demonstrating how to manage column names and values.
Data Visualization with ggplot2
Example
Creating a scatter plot using `ggplot2` by specifying the aesthetics (`aes`) and adding geometries such as `geom_point()` and `geom_smooth()`.
Scenario
An analyst wishes to visualize the relationship between house prices and the size of houses from a real estate dataset. Tidy Wizard helps the user create a scatter plot with `ggplot2`, ensuring proper labeling, scaling, and the addition of a trend line to show the underlying relationship.
Modeling with tidymodels
Example
Building a machine learning pipeline using tidymodels by first splitting the data (`initial_split()`), creating resamples (`vfold_cv()`), and fitting a model (e.g., `linear_reg()` or `random_forest()`).
Scenario
A data scientist needs to predict customer churn using historical customer data. Tidy Wizard walks them through setting up a data split for training and testing, using cross-validation, and building a logistic regression model with tidymodels. The wizard further explains how to evaluate the model using ROC curves and accuracy metrics.
Ideal Users of Tidy Wizard
Data Scientists and Analysts
Professionals who are already familiar with the basics of R and need assistance in mastering more complex data manipulation, visualization, or modeling tasks. They benefit from Tidy Wizard’s deep knowledge of the tidyverse and tidymodels, allowing them to efficiently solve intricate problems such as cleaning datasets, visualizing trends, or fine-tuning machine learning models.
