“onLoad.R”是否应该包含在描述文件的“整理”字段中？

Question

我需要在加载包时显示免责声明消息。看完帖子后

\n\n

库/包开发 - 加载时的消息
\n使用 .onLoad 加载依赖包

\n\n

我现在有一个zzz.R文件只包含

\n\n

.onLoad <- function(libname, pkgname){\n    packageStartupMessage(\'Regarding data obtained from www.retrosheet.org:\\n\n    The information used here was obtained free of charge from  \n    and is copyrighted by Retrosheet. Interested parties may\n    contact Retrosheet at "www.retrosheet.org"\', domain = NULL, appendLF = TRUE)\n}\n

\n\n

我有两个问题：

\n\n

\n

1. 我需要打电话到.onLoad某个地方吗？或者这会自动发生吗？

\n

2. 我正在使用文件Collate中的字段DESCRIPTION。是否zzz.R需要添加到该列表中？

作为检查，我运行以下代码。包启动消息在使用时出现install，但在调用时不会出现library，这是我所期望的。
