问题描述
我正在开发一个程序包，该程序包需要另一个程序包OpenMx的名称空间.该软件包仅可从其自己的存储库中获得，但是在Additional_repositories字段中指定此存储库不起作用.尝试在未安装OpenMx的情况下构建软件包时，我得到:
I am developing a package that requires the namespace of another package, OpenMx. This package is only available from it's own repository, but specifying this repository in the Additional_repositories field does not work. When trying to build my package without OpenMx installed, I get:
错误:依赖项'OpenMx'不可用于此类
ERROR: dependency 'OpenMx' is not available for blah blah
我的描述是否有问题，或者我需要做其他事情?
Is there a problem with my description, or something else I need to be doing?
我的描述文件的相关部分:
The relevant piece of my description file:

推荐答案
AFAIK Additional_repositories仍然是自由格式的字段，不会自动添加到download.packages()所引用的options("repos")中，因此不会自动添加到install.packages()或.
AFAIK Additional_repositories is still a free-form field and not automatically added to the options("repos") consulted by download.packages() and hence install.packages() or update.packages().
对于在CRAN之外添加 repos 的问题，我写了一个小帮手包 drat ，其中包括我在内的一些人用来在GitHub(可通过gh-pages轻松实现的默认"模式)或任何其他可通过HTTP访问的服务器上托管存储库公司或工作组中的本地服务器. Drat并没有做任何特别的困难，但是对于这种默认的添加用户存储库(例如openmx)的情况，您所需要的只是drat::addRepo("openmx")，其余的则是从默认值推断出来的(并假设帐户drat仓库) >存在).
For the very problem of adding repos beyond CRAN, I wrote a little helper package drat which a few people, myself included, use to host repos either on GitHub (a "default" mode as it is so easy via gh-pages) or any other http-accessible server---ie local servers within a company or workgroup. Drat does nothing particularly difficult, but for this default case of adding a repository of user, say, openmx, all you need is drat::addRepo("openmx") and the rest is inferred from defaults (and assumes a drat repo in account openmx exists).
我同时部署了两个用例:通过GitHub上的repos和工作本地的repo来安装较新的软件包.
I deploy both use cases: newer packages via repos at GitHub, and a work-local repo.
但是WRE说
这意味着它看起来在那里.奇怪的.回购在给定的URL上看起来合法.
which implies it looks there. Odd. And the repo looks legit at the given URL.
我在上述报价中向R Core发送了一个拼写错误的补丁.
Edit 2: And I sent a patch to R Core for the typo in the above quote.
