It's not clear from your message whether you have the file on your disk 
or not.  If you do, then instead of giving the name, try using the 
file.choose() function, e.g.

filename <- file.choose()
hof <- read_csv(filename)

That will open a standard dialog to allow you to specify the filename 
correctly.  If you don't know where to look for it, I can't help: 
presumably instructions are given in the book, but I don't have a copy. 
You'll just have to read more of it.
