正在创建R程序包，警告:程序包"---"是在R版本3.1.2下构建的

正在创建R程序包，警告:程序包

问题描述：

我正在创建自己的R包，它依赖于名为fOption的R包中定义的功能. 我的NAMESPACE文件有一行:

I am creating my own R package which depends on a function defined in R-package named fOption. My NAMESPACE file has a line:

  import(fOptions)

我的Description文件有一行:

My DESCRIPTION file has a line:

  Depends:  fOptions

但是，当我从终端使用R CMD CHECL --as-cran选项编译我的R包时，会收到以下警告消息:

However, when I compile my R package using R CMD CHECL --as-cran option from the terminal, I get the following warning messages:

   Found the following significant warnings:
   Warning: package ‘timeDate’ was built under R version 3.1.2
   Warning: package ‘timeSeries’ was built under R version 3.1.2
   Warning: package ‘fBasics’ was built under R version 3.1.2

我发现这些是fOptions的依赖项，正如其描述文件所述:

I found that these are dependencies of fOptions as its description file says:

  Depends: methods, timeDate, timeSeries, fBasics

这是否意味着我无法创建依赖于此特定R包(fOption)的R包?

Does this mean that I cannot create my R package that depend on this particular R package (fOption)?

我正在使用OS X版本10.9.4，而我的R版本是3.1.1(2014-07-10)-将其袜子给我".

I am using OS X Version 10.9.4 and My R version is 3.1.1 (2014-07-10) -- "Sock it to Me".

这些是警告，而不是错误，这意味着您可以继续进行，但解决这些问题会更好.

Those are warnings, not errors, which means you can proceed but it's better if you address them.

在这种情况下，您会收到警告，因为一些所需的软件包是使用比正在运行的R版本更新的R版本构建的.尽管可能不是问题，但这可能是一个问题，因此仅是警告.例如，如果其中任何一个软件包在较新的R版本中具有不同的行为，这将是至关重要的，尽管事实并非如此.

In this case, you're getting the warnings because a few of the packages you need were built using an R version that is newer than the R version you are running. This can potentially be a problem, though it's likely not a problem, hence it's just a warning. If any of those packages have a different behaviour in the newer R version, for example, this would be critical, though that's likely not the case.

我建议将您的R版本更新为3.1.2，这样可以避免这些警告，并且您将拥有较新的R版本:)如果您在无法更新R的环境中工作，那很好，您可以通过以下警告继续处理您的软件包，这只是不理想的.

I would suggest updating your R version to 3.1.2, and that would get rid of these warnings plus you'll have a newer R version :) If you are working in an environment where you cannot update R, then it's fine, you can go on with your package with these warnings, it's just non-ideal.
