r - 如何更改条形图中的 x 坐标？

Question

在前一个问题中，Ananda Mahto 告诉我如何创建条形图，
最好将 x 坐标从 0,2,4,6,8,10（在 graph1 中）更改为 0,1,2,3,4 ,5,6,7,8,9（在graph2中）
如何改变它？

set.seed(1)
A <- sample(0:10, 100, replace = TRUE)
stripchart(A, method = "stack", offset = .5, at = .15, pch = 19, 
       main = "Dotplot of Random Values", xlab = "Random Values")

我想要的是graph2.png而不是graph1.png。

graph1.png

graph2.png

Answer 1

A <- sample(0:9, 100, replace = TRUE)
stripchart(A, method = "stack", offset = .5, at = .15, pch = 19, 
           main = "Dotplot of Random Values", xlab = "Random Values",xaxt="n")
axis(1, at = 0:9, labels = 0:9)
