| Description: | Enables users to create visualizations using functions based on the data analysis task rather than on plotting mechanics. It hides the details of the individual 'ggplot2' function calls and allows the user to focus on the end goal. Useful for quick preliminary explorations. Provides functions for common exploration patterns. Some of the ideas in this package are motivated by Fox (2015, ISBN:1938377052). |

ezeda: A package for task oriented exploratory data analysis
Description
The ezeda package provides functions for visualizations for exploratory data analysis. Whereas graphic packages generally provide many functions that users assemble to create suitable plots, each ezeda function warps ggplot and other code to generate a complete plot for common exploratory data analysis task corresponding to a recurring pattern.

ezeda provides five categories of functions: tally, contribution, measure distribution, measure relationship, and measure trend

contribution functions
category_contribution
