因为ggplot画图后plot窗口看到的和保存文件后的图像,有时差异很大(取决于保存图像的大小、长宽比是否固定、dpi等),而读取文件并拼接的方式,子图的效果是已知且不会改变的,因此拼图后不会影响子图结构。此处代码就不画图了。 # library(grid) # library(gridExtra) # library(magick) # # 读取已经画好的图 # for...

The points outside the whiskers are marked as dots and are normally considered as extreme points. Setting varwidth=T adjusts the width of the boxes to be proportional to the number of observation it contains. Here is how to make a box plot in R: library(ggplot2) theme_set(theme_classic...
