简单来说,在你画图时你可能需要你的坐标轴标签或者其他地方格式是百分比形式,或者小数点后几位,或者特定的标签、单位、颜色色盘的设置等等,这些都可以通过scales包快速实现。 安装 # CRAN: install.packages("scales") # Github: devtools::install_github("r-lib/scales") 刻度 scales包提供了4个基本函数用于演示...

ggplot2 迄今是R里最受欢迎画图package,个人感觉最主要的一个因素就是layer叠加的语法结构(图层),类似于photoshop的图层概念。而且,ggplot2的变量映射aes也是很厉害。那么,就有个局限,每个变量只能映射一种scale,那怎么样在同一个图中出现两种或者多种color/fill scale的映射呢?
连续数据的坐标轴可以设置trans参数,它应该是通过调用scales包的相应trans类型实现的,比如scales中有log10_trans,ggplot2中可以直接设置trans=‘log10’,也就是将坐标轴的值进行log10转换。它其实就是scale_y_log10函数的效果: > p + scale_y_continuous(trans='log10'...
