Question

使用devtools创建的自定义程序包安装，加载，显示功能的帮助文件，但不提供功能。 This solution似乎不相关，因为我的软件包安装在.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()

错误：找不到功能“my.fun”

导致此行为的原因以及如何解决此问题？

你导出了这个功能吗？检查它是否在包运行中：

mypkg:::my.fun()
