Until now, we have changed the colors in a ggplot2 line and point graph. This example illustrates how to modify the colors of a boxplot graphic. For this, we can use the fill argument within the aesthetics of the ggplot function:
The graph below illustrates the list of line types available in R: library(ggpubr) show_line_types() In the next sections, we’ll illustrate line type modification using the example of line plots created with the geom_line(). However, note that, the option linetype can be also applied...

R绘图 第七篇:绘制条形图(ggplot2) 使用geom_bar()函数绘制条形图,条形图的高度通常表示两种情况之一:每组中的数据的个数,或数据框中列的值,高度表示的含义是由geom_bar()函数的参数stat决定的,stat在geom_bar()函数中有两个有效值:count和identity。默认情况下,stat="count",这意味着每个条的高度等于每组中...
