r - 无法在 R 版本 3 中加载“生存”

Question

对于这个问题，我在stackoverflow中尝试了很多，例如update.package，安装'codetools'，以及stackoverflow中的一些提示-我应该如何处理“package 'xxx' is not available”警告？但它不起作用。该软件包似乎已安装，但无法加载-

library(survival) 
## error:package ‘survival’ was built before R 3.0.0: please re-install it

Answer 1

@John 太棒了！我以前使用过 update.packages，但它不起作用——现在它起作用了！但是还是有警告——

package ‘survival’ was built under R version 3.1.2
