如何在 R 包中自动加载数据? [英] How to automatically load data in an R package?

问题描述

这可能是一个简单的答案，已被多次回答.我只是缺少搜索答案的术语.

This is likely an easy answer that's been answered numerous times. I just lack the terminology to search for the answer.

我正在创建一个包.当包加载时，我想立即访问数据集.

I'm creating a package. When the package loads I want to have instant access to the data sets.

假设 DICTIONARY 是一个数据集.

So lets say DICTIONARY is a data set.

我希望能够使用 DICTIONARY 而不是 data(DICTIONARY) 来加载它.我该怎么做呢?

I want to be able to do DICTIONARY rather than data(DICTIONARY) to get it to load. How do I go about doing this?

推荐答案

来自 R-exts.pdf (在线来源):

From R-exts.pdf (online source):

data"子目录用于存放数据文件，可以使用通过延迟加载或使用 data() 加载.(选择由DESCRIPTION"文件中的LazyData"字段:默认为不这样做.)

The ‘data’ subdirectory is for data files, either to be made available via lazy-loading or for loading using data(). (The choice is made by the ‘LazyData’ field in the ‘DESCRIPTION’ file: the default is not to do so.)

将以下内容添加到说明文件中即可:

Adding the following to the DESCRIPTION file should do it:

LazyData: true
