这 error message通常意味着R中的sample.split函数未被正确加载。你需要确保你已经正确安装了相应的包,并且已经使用library()或require()函数将其加载到R环境中。你可以尝试检查拼写错误,或者重新安装该包以解决这个问题。如果问题仍然存在,你可以尝试使用其他的分割数据集的函数,例如createDataPartition()或caret::createDataPartition()。

could not find function "adf.test"
The error message "could not find function 'adf.test'" means that the R interpreter cannot find the function "adf.test" in any loaded packages.
This error can occur if the package containing the function has not been installed or loaded. To solve this error, you need to install and load the appropriate package that contains the 'adf.test' function.
For example, if you want to use the 'adf.test' function from the 'tseries' package, you can install and load the package using the following R code:
```
install.packages("tseries")
library(tseries)
```
After you have loaded the 'tseries' package, you should be able to use the 'adf.test' function without encountering the "could not find function 'adf.test'" error.

在配置springboot打包工具时遇到"Could not find artifact"错误提示通常是由于缺少依赖项或者Maven仓库中没有相应的依赖包。解决这个问题的方法有以下几种:
1. 检查项目的pom.xml文件,确保依赖项的信息正确并且没有拼写错误。可以尝试使用其他可用的Maven仓库或者更新Maven仓库的镜像,以便能够找到所需的依赖项。同时,还要确保Maven的本地仓库已经正确配置并且可用。
2. 如果在特定的仓库中无法找到所需的依赖项,可以尝试切换到其他可用的仓库或者添加新的仓库到项目的pom.xml文件中。比如,引用中的问题可以尝试切换到其他可用的仓库或者检查该仓库的可用性。
3. 确保网络连接正常,能够访问Maven仓库。有时候,网络连接不稳定或者防火墙设置会导致无法正常连接到Maven仓库,从而出现"Could not find artifact"错误。可以尝试重新建立网络连接或者更改网络设置来解决这个问题。
综上所述,解决"Could not find artifact"错误的方法包括检查依赖项的配置、切换到其他可用的仓库、确保网络连接正常和检查Maven仓库的镜像设置。希望这些方法能够帮助您解决问题。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
