I use devtools and after I updated to R 3.3.1 I have this message every time I install something via Github.
Skipping install of 'PACKAGE' from a github remote, the SHA1 (123456) has not changed since last install.
Use `force = TRUE` to force installation
Anybody had this issue too?
It's the Issue while trying to install the packages try with below command:
install_github("Stat", force=TRUE)
It will force and help you to install.
Let me know if that works for you!
