我以前安装软件包时从未遇到过问题。
当我第一次尝试安装 plm 时包，它给了我一个错误说包 pbkrtest没有安装。所以我尝试安装 pbkrtest , 但是 install.packages("pbkrtest")没有用，它给了我这个错误信息:
install.packages("pbkrtest") Installing package into ‘C:/Users/Flo/Documents/R/win-library/3.2’ (as ‘lib’ is unspecified) Warning in install.packages : package ‘pbkrtest’ is not available (for R version 3.2.2)
我是从 https://cran.r-project.org/src/contrib/Archive/pbkrtest/ 手动下载的并将其放入相应的目录中。
继续，我现在可以安装 plm。尽管如此，我现在遇到了这个错误并且无法使用 plm 包:
library(plm)
Error in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) : object 'vI' not found
In addition: Warning message:
package ‘plm’ was built under R version 3.2.3
Error: package or namespace load failed for ‘plm’
这是我的 session 信息:

最佳答案
如果这仍然是一个问题并且您已更新到 3.3.0，请尝试使用 type="win.binary"参数。
install.packages("plm", dependencies=TRUE, type="win.binary")
关于r - loadNamespace 错误，使用包 plm 找不到对象 'vI'，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35942473/
