ggplot(mpg, aes(hwy)) + geom_histogram() 10. geom_bar() geom_bar()函数用来绘制条形图. 条形图使用高度来表示值,因此必须始终显示条形的底部以产生有效的视觉比较。注意其与直方图的区别. 这也是我们在数据可视化中使用频率很高的一个函数. 用法: geom_bar( mapping = NULL, data = NULL, stat = "co...
ggbarstats() In case you are not a fan of pie charts (for very good reasons), you can alternatively use ggbarstats() function which has a similar syntax. N.B. The p-values from one-sample proportion test are displayed on top of each bar. set.seed(123) library(ggplot2) ggbarstats...

The color (or fill) is based upon the response column.p = ggplot(data=df, aes(x=factor(1), y=Summary, fill = factor(response) ),) Geometric Objects The geometric object (or geom) in this case will be used to create a bar chart. In ggplot2 this is identified as geom_bar. p...
