geom_labelto add a label: framed text Note that theannotate()function is a good alternative that can reduces the code length for simple cases. # librarylibrary(ggplot2)# basic graphp <-ggplot(mtcars,aes(x =wt,y =mpg))+geom_point()# a data frame with all the annotation infoannotation...
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...
level : level of confidence interval to use. Default value is 0.95 Regression line To add a regression line on a scatter plot, the function geom_smooth() is used in combination with the argument method = lm. lm stands for linear model. p <- ggplot(cars, aes(speed, dist)) + geom_poi...
How to Label Outliers in Boxplots in ggplot2, This article offers a detailed illustration of how to name outliers in ggplot2 boxplots. Step 1: Construct the data frame. Create the following data frame first, which will include details on the 60 distinct basketball players who played for th...
You no longer have to worry about quoted and unquoted column names when using ggplot2, thanks to the latest version of the rlang package
With print() If you are an advanced R user, you probably know the lattice and the ggplot2 packages. They allow you to plot elegant graphics with less code (Hocking, 2009 and Sueur, 2010). If you know these two packages, you should hardly use plot() for y
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...
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. The first argument is a data frame. Here we want to usehome_data. ...
