Attached is a scheme example how to do this (it checks the duration-log, i.e. 
a quarter rest has a 2-log of 2, an eighth rest has a 2-log of 3, since 
1/8=2^(-3)). Quarter and eighth rests are printed the way you want them, all 
other rests are printed as usual.

The example assigns that function globally. If you want it only for some 
parts, you can simply remove the \layout block and do:

\relative {
    e4. r8 e4 r4
    \override Rest #'stencil = #ly:rest-interface::dot-rests
    e4. r8 e4 r4
    \reset Rest #'stencil
    e4. r8 e4 r4
}

Also note that I changed the circle call from a radius of 0.6 and a thickness 
of 0 to a radius of 0.55 and a thickness of 0.1 (half of the thickness will be 
outside the radius, half of it inside!), because then you get nice anti-
aliasing and the circle will look really rounded.

I've also added that snippet to the LSR, together with some explanations:
