如何在我自己的R包中包含一个需要的包？

Question

I built my own package and everything is working well. However, I need to load another packages when I load my package. That is, I want R loads all requires packages automatically when I load my package like this:

library(mypackage)
loading requrie packages:
first package 
second package 

Is there any easy way?

Answer 1

Add them in your DESCRIPTION file, section Depends .

Depends:
  first package,
  second package

You should read the book R Packages .
