R直方图图中每个箱中的实例数(R histogram number of instances in each bin on plot)

R直方图图中每个箱中的实例数(R histogram number of instances in each bin on plot)

我想看到每个bin的实例数量也显示在图表上

set.seed(1) x<-rnorm(1:100) hist(x)

I would like to see the number of instances for each bin show up on the graph as well

set.seed(1) x<-rnorm(1:100) hist(x)

最满意答案

试试这个

set.seed(1) x<-rnorm(1:100) y <- hist(x, plot=FALSE) plot(y, ylim=c(0, max(y$counts)+5)) text(y$mids, y$counts+3, y$counts, cex=0.75)

这使：

Try this

set.seed(1) x<-rnorm(1:100) y <- hist(x, plot=FALSE) plot(y, ylim=c(0, max(y$counts)+5)) text(y$mids, y$counts+3, y$counts, cex=0.75)

which gives:
