这个错误说明R无法找到名为"anscombe.test"的函数。可能的原因是您没有正确加载包含该函数的包。您可以尝试使用以下命令加载包:
```
library(car)
```
这将加载car包,其中包含了anscombe.test函数。如果您已经加载了car包但仍然出现这个错误,请检查您的R版本是否过旧,或者尝试重新安装car包。

Error in anscombe.test(x) : could not find function "anscombe.test"
The error message "could not find function 'anscombe.test'" means that the function 'anscombe.test' is not available in the R environment. This could be due to various reasons such as:
1. The package containing the function is not installed: If the function is part of a package, you need to first install the package using the command install.packages("package_name") and then load it into the R environment using library(package_name).
2. The function is not loaded into the R environment: If the package containing the function is already installed, you need to load it into the R environment using library(package_name).
3. The function doesn't exist: It is possible that the function 'anscombe.test' does not exist in any package and hence cannot be called.
To resolve the error, you can try the following steps:
1. Check if the function is part of a package and install/load the package accordingly.
2. Check the spelling of the function name and ensure it is correct.
3. Look up the documentation or help file for the function to ensure you are calling it correctly.
4. If none of the above steps work, it might be that the function does not exist and you need to find an alternative method to achieve your goal.
sns.regplot(x="x",y="y",data=anscombe.query("dataset == 'III'"),ci = None ,robust=True)
这段代码使用 seaborn 库中的 regplot 函数画了 Anscombe 数据集中第 III 组的散点图和回归线。其中,x, y, data 分别表示 x 轴数据、y 轴数据、使用的数据集。ci = None 表示不显示置信区间,robust=True 表示使用鲁棒回归方法,可以降低离群值对回归结果的影响。
