如何处理r中sens.slope中的NA？

Question

如果我有此数据：

一切正常，没问题。但是在我的真实数据中有NA。

library(trend)
v <- runif(100) * 1:100
func <- function(x,na.rm=T) { unlist(sens.slope(x)) }
func(v,na.rm=T)

我收到此错误：  na.fail.default（x）中的错误：对象

中缺少值

Answer 1

首先设置v <- v[!is.na(v)]（在向v提供func之前），它应该运行良好。

否则请调整您的功能，在这种情况下，无需执行以上操作

func <- function(x,na.rm=T) {
 if(sum(is.na(x)) == length(x)) return(NA)
 if(na.rm) x <- x[!is.na(x)]
 unlist(sens.slope(x)) 
}
