License --- Project Overview This project provides a single, self-contained R script ( Wine Quality Analysis.R ) that: Automatically installs and loads required packages Downloads red and white wine quality data from the UCI repository Parses semicolon-delimited files with explicit decimal handling Merges into one tidy data frame with a type factor Creates multiple exploratory plots to uncover chemical and quality patterns Performs Principal Component Analysis (PCA) on standardized attributes Fits a linear regression predicting wine quality from key predictors Outputs summary statistics, diagnostic plots, and fitted vs. actual comparisons Ideal for data scientists, statisticians, and wine enthusiasts seeking a reproducible pipeline for exploring chemical correlates of perceived wine quality. --- Features 1. Data Ingestion & Cleaning Downloads CSVs for red & white wines Enforces consistent numeric types via read delim() with explicit locale 2. Exploratory Visualizations Bar chart of quality counts by type Jittered scatter of alcohol content vs. quality Faceted boxpl","default_branch":null,"files":null,"tree":[],"storefront":"/r/hoangsonww","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/hoangsonww/Wine-Quality-Data-Analysis/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
