Question

我试图更新一些R包，因为RStudio显示它们可以更新。更新后，只需删除两个包。（rgdal和spatstat）。最近几次发生了同样的事情。这里发生了什么？

> install.packages(c("data.table", "rgdal", "spatstat"))
Installing packages into ‘C:/Users/Patrick/Documents/R/win-library/3.4’
(as ‘lib’ is unspecified)
also installing the dependency ‘spatstat.data’


  There is a binary version available but the source version is later:
              binary source needs_compilation
spatstat.data  1.1-0  1.1-1             FALSE

Answer 1

您可以使用

找到包含已安装软件包的目录

.libPaths()

哪个应该给你这样的东西：

"/Library/Frameworks/R.framework/Versions/3.3/Resources/library"

如果您看到rgdal或spatstat，我会将其删除，然后再次尝试安装。

为什么R包更新后会被删除？
