You write your ggplot2 code as if you were putting all of the data onto one plot, and then you use one of the faceting functions to indicate how to slice up the graph. There are two main facet functions in the ggplot2 package: facet_grid(), which layouts panels in a grid. It crea...
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...

In case we want to draw our data using the functions of the ggplot2 package, we also have to install and load ggplot2:install.packages("ggplot2") # Install ggplot2 package library("ggplot2") # Load ggplot2 packageNow, we can draw our data as shown below....
The hardest thing to understand in ggplot2 is theaes()function. Theaes()function enables you to create a set of mappings from data (in your dataframe) to the aesthetic attributes of the plot. That doesn’t make sense to many people, so let me quickly explain. ...
