[問題敘述]:
我自己寫一隻package，會用到其他人的package,
於是在project的description這個檔案裡填上Depends: ...
我知道如果是從cran下載來的pkgs可以在dependencies選擇要不要裝需要的pkgs
但如果沒打算上傳cran，就是用zip傳給人家裝
install.packages(..., dependencies="Depends") 就不太成功,
看了說明換成NA或TRUE其他的都不行
Google了一下，不多這樣的問題，而且有些時間了

我以為可以更簡單的解決.
例如require(mylib) 之中設定個參數. 但好像沒有找到
