R 需要更新的包的列表

如何生成需要更新的软件包列表，即包含软件包名称、当前安装版本和存储库中可用版本的表

我已尝试，

installed.packages（）

，

update.packages（）

，但我无法强制这些函数生成所需的输出

---

注意，我不想实际更新这些包；我只想看看上面提到的列表。

您知道函数

old.packages（）

从

帮助（update.packages）

：

---

看看

old.packages（）

。在我的系统中，我有：

R> old.packages()

以八秒之差击败你；-）@DirkEddelbuettel是的，但我的答案更大：PBut来自一个明显无效的系统，因为你展示了一个过时的Rcpp在使用中。谢谢！或者我可以使用更短的

old.packages（）[，c（“Installed”，“ReposVer”）]

.Hi@Dirk！这很奇怪，但我看到加文在顶部的答案，直到现在才注意到你的答案，尽管他的分数较低：-）也要归功于你：）德克，谢谢你的答案。OT：作为MCMC大师，我想问你，你是否有从R运行JAGS的经验。我正在努力解决R2jags和runjags包中的bug。但您可能正在使用一些Rcpp魔法来代替它？：-）@托马斯：我想你应该问一个新问题。德克，我很想问，但我担心“什么是运行JAG的最佳方式”这样的问题会在不到5秒钟内结束：-）更不用说“德克，真正的大师在用什么”这样的问题了：-）
