如何在缺少值的地方连接点? [英] How to connect dots where there are missing values?

问题描述

让我们举个例子:

       test=c(1,5,NA,5,4,1,NA,3,3,5,4,2)

      plot(test,type="l")

这将绘制测试但不会连接点.是否有一种方法可以忽略NA并连接点，从而获得漂亮的图形?

This will plot test but will not connect the dots.Is there a way we can ignore the NAs and connect the dots so we get pretty graph?

推荐答案

无法忽略丢失的值.您需要将它们替换为插值.

There isn't a way to ignore the missing values. You need to replace them with interpolated values.

# using base packages only
plot(approx(test, xout=seq_along(test))$y, type="l")
# or, using zoo
library(zoo)
plot(na.approx(test), type="l")
