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...
