[问题叙述]:
我自己写一只package，会用到其他人的package,
于是在project的description这个档案里填上Depends: ...
我知道如果是从cran下载来的pkgs可以在dependencies选择要不要装需要的pkgs
但如果没打算上传cran，就是用zip传给人家装
install.packages(..., dependencies="Depends") 就不太成功,
看了说明换成NA或TRUE其他的都不行
Google了一下，不多这样的问题，而且有些时间了

我以为可以更简单的解决.
例如require(mylib) 之中设定个参数. 但好像没有找到
