如何自动在R包中加载数据? [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，已经被无数次地回答了.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.

我正在创建一个包裹.当程序包加载后，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.

所以可以说字典是一个数据集.

So lets say DICTIONARY is a data set.

我希望能够执行DICTIONARY而不是data(DICTIONARY)使其加载.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(

From R-exts.pdf (online source):

"data"子目录用于数据文件，使其可用 通过延迟加载或使用data()加载. (由 "DESCRIPTION"文件中的"LazyData"字段:默认为 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.)

在说明文件中添加以下内容即可:

Adding the following to the DESCRIPTION file should do it:

LazyData: true
