“r1” means a whole (=4/4) rest, not a whole measure rest.

Yes, “r2.” has the correct length. But you probably wanted to follow the 
engraving rule (as you should) and have a whole rest *symbol*. For that 
you have to tell LilyPond that it’s a *full measure* rest by using a 
capital R: “R2.” LilyPond will then use the correct symbol and center it 
horizontally.
