使用 Nile 数据集的 tsoutliers 包出现语法错误 [英] Syntax error with tsoutliers package using Nile dataset

问题描述

我正在尝试使用 tsoutliers 包在时间序列中查找异常值.

I'm trying to locate outliers in a time series using the tsoutliers package.

我使用的是经典的 Nile 数据集(您可以在这里找到:https://vincentarelbundock.github.io/Rdatasets/datasets.html) 并且我没有成功地让 tso() 函数工作.

I'm using the classic Nile dataset (which you can find here: https://vincentarelbundock.github.io/Rdatasets/datasets.html) and I'm unsucessfully getting the tso() function to work.

我的代码是:

nile.outliers <- tso(Nile,types = c("AO","LS","TC"))

但是，我收到了这个语法错误，或者我认为这是一个语法错误:

However, I get this syntax error, or what I assume is a syntax error:

tso0(x = y, xreg = xreg, cval = cval, delta = delta, n.start = n.start, 中的错误:试图从不是 S4 对象的对象(类data.frame")中获取插槽y"

Error in tso0(x = y, xreg = xreg, cval = cval, delta = delta, n.start = n.start, : trying to get slot "y" from an object (class "data.frame") that is not an S4 object

如果有人能帮我解决这个问题，那就太棒了！谢谢！

If anyone can help me figure out this problem that would be amazing! Thanks!

推荐答案

吹毛求疵:这不是语法错误(可能来自 R)，而是来自 tso0 函数的运行时错误在 tsoutliers 包中.

A quibble: that's not a syntax error (which would come from R), it's a run-time error from the tso0 function in the tsoutliers package.

但是从您对从何处获取数据的描述来看，当 tso 想要一个 "ts" 对象时，您似乎正在传入一个数据框.您不需要下载数据，它内置于 R 中；所以你删除你创建的坏的，并使用内置的:

But from your description of where to get the data, it looks as though you are passing in a data frame, when tso wants a "ts" object. You don't need to download the data, it's built in to R; so you remove the bad one you created, and use the built-in one:

rm(Nile)
nile.outliers <- tso(Nile,types = c("AO","LS","TC"))
