仅在R中绘制颜色点以表示0＆1和1

Question

我有兴趣将一行1和0作为一行绿色和红色点。我是R的新手，并没有找到一个绘图解决方案来做到这一点。示例：numbers = c(1,0,0,1,1,1,1,1,1,0,1,0,1,0)。将其绘制为(green dot, red dot, red dot, green dot, green dot,...)

的单行

Answer 1

plot(x = seq_along(numbers),
     y = rep(1, length(numbers)),
     pch = 19,
     col = c("red","green")[1 + (numbers == 1)],
     ann = FALSE,
     axes = FALSE)
