将向量绘制为r中的线

发布于 2025-02-09 21:15:31 字数 359 浏览 1 评论 0原文

我有这样的向量：

vec<-c(NA,1,1,NA,NA,NA,1,NA)

我该如何绘制这样的绘制：

我已经准备好了一个情节，我只想在当前的情节中添加类似的行。因此，我尝试使用行：

line(vec)

但是我有一个错误。我该如何实现我想做的事情？

原文

I have a vector like this:

vec<-c(NA,1,1,NA,NA,NA,1,NA)

How can I plot it like this:

I already have a plot ready, I just want to add a line like above to my current plot. So I tried using line:

line(vec)

But I am having an error. How can I achieve what I want to do?

这样的东西？
注意seq_along作为x轴坐标的使用。类型“ n”的图，这意味着没有图，只需设置适当宽度和高度的绘图区域即可。

vec<-c(NA,1,1,NA,NA,NA,1,NA)

plot(seq_along(vec), vec, type = "n", xlab = "", ylab = "")
lines(seq_along(vec), vec, xlab = "", ylab = "")
points(seq_along(vec), vec, pch = 19, xlab = "", ylab = "")

数据集cars可能不是最好的示例，因为轴范围不匹配vec的s，但这是一个图。

vec <- c(NA,1,1,NA,NA,NA,1,NA)

plot(cars, main = "Stopping Distance versus Speed", xlim = c(0, 25))
lines(seq_along(vec), vec, xlab = "", ylab = "")
points(seq_along(vec), vec, pch = 19, xlab = "", ylab = "")

Something like this?
Note the use of seq_along as x axis coordinates. And of a plot of type "n", meaning no plot, just set the plot area with appropriate width and height.

vec<-c(NA,1,1,NA,NA,NA,1,NA)

plot(seq_along(vec), vec, type = "n", xlab = "", ylab = "")
lines(seq_along(vec), vec, xlab = "", ylab = "")
points(seq_along(vec), vec, pch = 19, xlab = "", ylab = "")

The data set cars is probably not the best example since the axis ranges do not match vec's, but here is a plot.

vec <- c(NA,1,1,NA,NA,NA,1,NA)

plot(cars, main = "Stopping Distance versus Speed", xlim = c(0, 25))
lines(seq_along(vec), vec, xlab = "", ylab = "")
points(seq_along(vec), vec, pch = 19, xlab = "", ylab = "")
