将自定义包添加到Azure Machine Learning Studio

Question

我需要在azure机器学习工作室使用函数tsCV来评估预测模型，但我得到了错误

could not find function "tsCV

我正在尝试更新预测包，但没有加载包。我按照本教程http://blog.revolutionanalytics.com/2015/10/using-minicran-in-azure-ml.html和https://blog.tallan.com/2016/12/27/adding-r-packages-in-azure-ml/但我没有得到相同的结果。没有包加载。

我需要一个包含R代码的软件包的示例，该代码适用于Azure ML或更新预测包以使用tsCV功能。

Answer 1

我已经安装了最新版本的预测包，以下是我在安装过程中遵循的步骤。

1. 下载CRAN的最新版本
2. 确保tsCV在本地工作
3. 压缩所有依赖项+预测包
4. 将所有生成的拉链压缩在一起并上传到AMLStudio
5. 运行以下代码：
