Visualization (可视化)用来探索数据,建立假设并进行假设检验,然后再不断重复。 主要用到ggplot2包。 详细学习见绘图文集。 概览: image.png 参考:
Data Science: Visualization Overview The fact that it can be difficult or impossible to notice an error just from the reported results makes data visualization particularly important. This course will explore how failure to discover these problems often leads to flawed analyses and false discoveries. ...
Data visualization helps by presenting data in the most effective approach of graphical representation. Data visualization takes the raw data, models it, and delivers the data as one of the key steps in the business intelligence process so that conclusions can be drawn. Data scientists are designin...
