Coursera 课程“Mastering Data Visualization with R”是一门深入讲解如何利用 R 语言从数据中提取有意义见解的课程。
该课程系统地介绍了 R 中的三种主要数据可视化体系：
A. **Base R Graphics (基础绘图系统)**:
* **单变量图表**:
* 连续变量：直方图、密度图、箱形图
* 离散变量：条形图
* **双变量图表**:
* 两个连续变量：散点图
* 一个连续变量，一个离散变量：箱形图、饼图、点图、条带图
* 两个离散变量：马赛克图、堆叠条形图
* **时间序列**: 折线图
B. **Lattice Package (Lattice 包)**:
* 该部分涵盖了直方图、密度图、箱形图、条形图、散点图、点图、条带图等多种图表类型。
C. **GGPlot2 Package (GGPlot2 包)**:
* 重点讲解 `ggplot()` 函数的七个图层及其应用。
* 包含一个实践项目：根据预算从包含 54000 颗钻石的数据集中选择钻石。
* **常用图表**: 直方图、密度图、箱形图、条形图、散点图、点图、条带图。
学生评价普遍积极，认为该课程“非常透彻，涵盖所有细节，不留任何遗漏”，“节奏好，小片段清晰”，“解释清晰连贯”，“结构良好且非常有帮助”。其中一位学生称赞讲师“非常勤奋地说明演示过程中按下的所有按键，这一点常常被忽视”。另外，也有学生提到，“Sandeep Kumar 教授在 Udemy 提供的所有课程都非常出色，尤其是在数据分析和可视化方面。”

This course will help you draw meaningful knowledge from the data you have.Three systems of data visualization in R are covered in this course:A. Base Graphics B. Lattice package C. GGPlot2 A. Types of graphs covered in the course using the base R package:Single Continuous Variable: Histogram, Density Plot, Box-Whisker Plot Single Discrete Variable: Bar Chart Two Continuous Variable: Scatter PlotTwo Variable: One Continuous, One Discrete: Box-Whisker Plot, Pie Chart, Dot Chart, Strip Chart Two Variables: Both Discrete: Mosaic Plot, Stacked Bar Plot Time series: Line ChartsB. Types of graphs covered in the Lattice package:Histogram, Density Plot, Box-Whisker Plot, Bar Chart, Scatter Plot, Dot Chart, Strip ChartC. Graphs covered in GGPlot2 package:In this section you will learn about 7 layers in ggplot() and how to use these. In addition there is a project of selecting a diamond from the dataset of 54000 diamonds, based on my budget. Commonly Used Graphs: Histogram, Density Plot, Box-Whisker Plot, Bar Chart, Scatter Plot, Dot Chart, Strip ChartWhat are other students saying about this course?Very thorough. Covers all the details without glossing over anything. Good consistent pace and nice short segments. Very diligent in always saying what keys he was pressing during the demos, which is often overlooked. Excellent course. (5 stars by Roger Holeywell)Explanations are clear and coherent. This course is well structured and very-very useful. Thank you so much for your help! (5 stars by Martina Katalin Szabó)Todos os cursos oferecidos pelo Prof. Sandeep Kumar na Udemy são excelentes, especialmente em análise e visualização de dados.(5 stars by Jose Maria Nogueira da Costa )
