Hi, @Raque,
I have this similar experience before. I will share my way to solve this kind of problem.
- In the console, type
.libPaths()
orfind.package
(@cderv) and get the package path in your computer. - Go to the path and delete the package folder
- Reuse
install.package()
function to try.
If in this way, it also fail. I suggest you can install this package from github in the developing version.
