我遇到类似的错误.复制它的最低条件似乎是:

I get a similar error. Minimal conditions to reproduce it seem to be:

1. Depend在包装x(在我的情况下为reshape)上
2. 在小插图中装入一个包y(在我的情况下为plyr)，该包也可以导入或依赖于x.

1. Depend on a package x (in my case reshape)
2. In your vignette load a packge y (in my case plyr) that also imports or depends on x.

如果在包装构建或检查过程之外构建小插图，则该小插图会很好地构建，但是会抛出您以其他方式表示的错误.该错误也是R版本的，并且可能是特定于站点的，因为在尝试在另一台计算机上构建软件包时，R 3.2.0消除了该错误.

The vignette builds fine if you build it outside of the package building or checking process, but throws the error that you indicate otherwise. The error is also R version and maybe site specific, since it goes away with R 3.2.0 when trying to build the package on a different machine.
