Error in auto.arima(weather_ts) : could not find function "auto.arima" >

这个错误是因为在你的代码中没有加载`forecast`包,而`auto.arima()`函数是`forecast`包中的函数。你需要在执行`auto.arima()`函数之前,先加载`forecast`包。
可以使用以下代码加载`forecast`包:
```
library(forecast)
```
如果你没有安装`forecast`包,可以使用以下代码进行安装:
```
install.packages("forecast")
```
安装后再加载即可使用`auto.arima()`函数。

Error in auto.arima(log(BJsales)) : could not find function "auto.arima"
这个错误提示表明你使用的 R 包中没有 `auto.arima` 函数。`auto.arima()` 函数属于 `forecast` 包中的一个函数,因此在使用该函数前需要先安装并加载 `forecast` 包。你可以按照以下步骤来解决该问题:
1. 安装 `forecast` 包。
```R
install.packages("forecast")
```
2. 加载 `forecast` 包。
```R
library(forecast)
```
3. 然后你就可以使用 `auto.arima()` 函数了。
```R
auto.arima(log(BJsales))
```
could not find function "auto.arima"
It seems like you are trying to use the "auto.arima" function in R, but the function cannot be found.
This could be due to a few reasons:
1. The "forecast" package, which contains the "auto.arima" function, may not be installed. You can install it by running the command "install.packages('forecast')" in R.
2. The package may be installed, but not loaded into your current R session. You can load it by running the command "library(forecast)".
3. There may be a typo or error in the way you are trying to call the function. Make sure the function name is spelled correctly and that you are passing in the correct arguments.
I hope this helps! Let me know if you have any further questions.
