Does concrete have an R value. 8 inches is equal to about a single pane of glass. Not much at all...?

Yes. Don't know for sure but its pretty low.
however note that R value depends on the thickness. You double the thickness you double the R value.

What is the R value of concrete?
The R value of a material is the thermal resistance of the material, so is dependent on the material's thickness. R is also the inverse of a material's thermal conductivity U. To work it out you need the k value ( the thermal conductivity) of the material and the thickness, then R=thickness/k. The k value for structural concrete (of density 2300kg/m3) is 1.6 W/mK (Units: Watts / (metre x degrees Kelvin) so for a thickness 100mm (0.1m) of this concrete, R=0.06 m2°C/W. Note that the R value in imperial units will not be the same. Check the units for any R value of any material that is given.

A glass dropped on the floor is more likely to break if the floor is concrete than if it is wood why?
A glass dropped on a concrete floor is more likely to break than if it was dropped on a wood floor because the concrete has no bend to it. A wood floor might help absorb some of the impact by bending slightly when the glass hit it.
