自定义 R 包加载，显示帮助但不提供功能

Question

我使用 devtools 创建的自定义包安装、加载、显示功能的帮助文件，但不提供功能。 This solution 似乎不相关，因为我的包安装在 .libPaths().

# from the parent directory of the created package
install.packages("mypkg", repos = NULL, type = "source")
# ...
# * DONE (mypkg)
require(mypkg)
# Loading required package: mypkg
?my.fun        # displays the function help documentation correctly
my.fun()

Error: could not find function "my.fun"

是什么原因导致此行为以及如何解决？

你导出函数了吗？检查它是否在包运行中：

mypkg:::my.fun()
