I faced the same problem. I am using the latest version of R and RStudio and all of the installed packages are up-to-date.
Now, talking about the error in installation of packages. Follow the steps below and you will have R Notebook up and running:
- Run the command
install.packages("rmarkdown", dependencies=TRUE)
You will observe several messages on the console during installation. Browse through them and jot the ones where there is ERROR in installation of some other dependent package. In my case, it was 'backports'. The error message will be like this:
ERROR: compilation failed for package 'backports'
It can be different in your case but the point is to note down the name of the package that is facing compilation issues. Use an editor(npp) to save the name of the package.
- Once you get the name of the package, execute the following command:
install.packages("backports", type="binary")
- After successful execution of the above command, go to File drop down and select R Markdown. Go with auto installation of the rmarkdown and rprojroot packages. They will be successfully installed and you can now use R Notebook
Let us know if this solution worked for you.
