How to Make a Histogram with ggplot2 Now we can create the histogram. Regardless of the type of graph we are creating in ggplot2, we always start with theggplot()function, which creates a canvas to add plot elements to. It takes two parameters. ...
ggplot2是R中新颖的数据可视化包,这得益于Leland Wilkinson在他的著作《The Grammar of Graphics》中提出了一套图形语法,把图形元素抽象成可以自由组合的成分,Hadley Wickham把这套想法在R中实现。 1. How to use qplot 函数qplot()是ggplot2中十分常用的函数,使用它可以绘制丰富多彩的图形,并且通常只需要一行代码可...
在上面的例子中,各种属性映射由ggplot函数执行,只需要加一个图层,使用geom_point()告诉ggplot要画散点,于是所有的属性都映射到散点上。 geom_point()完成的就是几何对象的映射,ggplot2提供了各种几何对象映射,如geom_histogram用于直方图,geom_bar用于画柱状图,geom_boxplot用于画箱式图等等。 不同的几何对象,要求的...

How to create a dotted vertical line using ggplot2 in R - To create a vertical line using ggplot2, we can use geom_vline function of ggplot2 package and if we want to have a dotted vertical line then linetype will be set to 3 inside the same function. To
The goal of this article is to describe how to change the color of a graph generated using R software and ggplot2 package. A color can be specified either by name (e.g.: “red”) or by hexadecimal code (e.g. : “#FF1234”). The different color systems available in R are describe...
