Roxygen2 记录函数的依赖关系

Question

我想知道如何记录一个函数需要第二个函数或包。是否有特定的标签可以这样做，还是我应该在功能描述中这么说？

#' @title Downloads stuff from that place
#' 
#' @details Maybe document the dependency here?
#' 
#' @param stuff Thing to be downloaded
#' @param save_to Where to place the thing
#' @return Nothing. Called for its side effect

download_stuff = function(stuff, save_to) {

    require('RCurl')               # How do document this?

    # thing = download stuff using RCurl
    # write thing to save_to
}

我最终使用了this post中显示的想法，并写了以下内容：

#'@section Dependencies: 
#'  \describe {
#'    \item{package_1}
#'    \item{package_2}
#'    \item{package_n}
#'  }
