However, in most cases you start with ggplot(), supply a dataset and aesthetic mapping (with aes()). You then add on layers (like geom_point() or geom_histogram()), scales (like …

ggplot2的语法与base r不同。 根据基本元素，默认的ggplot需要指定三样东西: 数据，美学和几何形状。 我们总是通过调用ggplot (data = df)来定义绘图对象，它只告诉ggplot2我们将处理该数 …

A system for 'declaratively' creating graphics, based on "The Grammar of Graphics". You provide the data, tell 'ggplot2' how to map variables to aesthetics, what graphical primitives to use, and …

如果将数据定义在 ggplot() 中，那么所有图层都可以共用这个数据；如果将数据定义在 geom_xyz() 中，那么这个数据就只供这个几何对象使用。 掌握了数据、几何对象、图形属性和图层的概 …

ggplot ()：此函数才是 ggplot2 的精髓，远比qplot ()强大，可以一步步绘制十分复杂的图形。 由 ggplot2 绘制出来的ggplot图可以作为一个变量，然后由print ()显示出来。 图形类型 根据 数据 …

As the first step in many plots, you would pass the data to the ggplot() function, which stores the data to be used later by other parts of the plotting system.

在这里，我们为 ggplot () 函数提供了两个参数：数据data和映射mapping。 data 参数告诉 ggplot 在哪里可以找到它要使用的变量。 mapping告诉ggplot映射到坐标轴的具体有哪些坐标。 …
