安装R软件包时出现错误？

Question

自从我更新软件包以来已经有一段时间了。今天早晨，当我尝试使用update.packages(ask = F)时，它下载了软件包并试图运行更新，但发出了许多警告。在这里看到一些瞥见

> update.packages(ask = FALSE)

  There are binary versions available but the source versions are later:
          binary source needs_compilation
backports  1.1.7  1.1.9              TRUE
maptools   1.0-1  1.0-2              TRUE

  Binaries will be installed

package ‘backports’ successfully unpacked and MD5 sums checked

不知道发生了什么，但是当我尝试加载程序包时，我收到了消息，例如图片中附带的消息。无论如何，请继续前进，因为看来我已经失去了一切。
