需要更新的软件包列表答案

【问题标题】：List of packages that need an update需要更新的软件包列表
【发布时间】：2014-03-18 11:15:35
【问题描述】：

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

我尝试过hack packageStatus()、installed.packages()、update.packages()，但我无法强制这些函数产生所需的输出。

请注意，我不想真正更新这些包；我只想看看上面提到的列表。

【问题讨论】：

标签： r updates r-package

【解决方案1】：

你知道old.packages()这个函数吗？

来自help(update.packages)：

 ‘old.packages’ indicates packages which have a (suitable) later 
 version on the repositories whereas ‘update.packages’ offers to
 download and install such packages.

德克，谢谢你的回答。 OT：作为 MCMC 专家，我想问一下您是否有从 R 运行 JAGS 的经验。我正在努力解决 R2jags 和 runjags 包中的错误。但是您可能正在使用一些 Rcpp 魔法？ :-)
@Tomas 我认为你应该为此提出一个新问题。
Dirk，我很乐意，但我担心“什么是运行 JAGS 的最佳方式”之类的问题会在 5 秒内关闭 :-) 更不用说像“Dirk，什么是真正的大师使用“:-)

【解决方案2】：

看看old.packages()。在我的系统上我有：

领先你八秒 ;-)
@DirkEddelbuettel 是的，但我的答案更大：P
但是来自一个明显无效的系统，因为您显示了一个过时的 Rcpp 正在使用中。
谢谢！或者我可以使用更短的old.packages()[, c("Installed","ReposVer")]。
嗨@Dirk！这很奇怪，但我在顶部看到了 Gavin 的答案，直到现在才注意到你的答案，即使他的分数较低 :-) 也要归功于你 :)
