Error in loadNamespace, object 'vI' not found with package plm

I never had problems with installing packages before. When I first tried to install the plm package, it gave me an error saying that package pbkrtest was not installed. So I tried installing pbkrtest, but install.packages("pbkrtest") did not work, it gave me this error message:

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)

I downloaded it manually from https://cran.r-project.org/src/contrib/Archive/pbkrtest/ and put it into the respective directory.

Moving on, I could now install plm. Nevertheless, I am now stuck with this error and cannot use the plm package: 

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’

If this is still an issue and you have updated to 3.3.0, try using the type="win.binary" argument.

install.packages("plm", dependencies=TRUE, type="win.binary")

I had the same problem with another package (proast65.5).

The solution that worked for me was:

Go to the map with the package and open the file DESCRIPTION. In my DESCRIPTION file there was a line starting with Imports: I loaded all the package mentioned in that line with 

install.packages(package-name)

After that, I was able to load my library in R with the command 

library(proast65.5)
