Chapter 8.4: Example for path expansion

[moritzkoerber]

Thanks for the great chapter 8.4 How to transfer your library when updating R, it helped me a lot to do a clean update! I stumbled upon one line in it, maybe you could consider clarifying it:

"You can also alternatively set R_LIBS_USER to a different path; but make sure to include the %v wildcard. e.g. ~/R/library/%v. The %v is automatically expanded to the major and minor version of R, so with R 3.5.1 this path becomes ~/Library/R/3.5/library."

While ~/Library/R/3.5/library is, of course, the default for R_LIBS_USER with R 3.5.1 (as explained in the chapter before), it sounds to me like "this path" refers to the given example,~/R/library/%v, which would expand to ~/R/library/3.5.
