The answer depends on what you mean by "r values".
insulation
it is a good thing i think R Value is the thermal resistance of a given material. The higher the R Value the more thermal resistance and the better the insulation. So, an R48 roof system is warmer than an R32 roof system. All insulation materials are rated by their R Value. An inch of rigid insulation has a higher R Value than an inch of fiberglass insulation. Check with the insulation manufacturer for the R Value.

To convert U vals To R Vals 1/u = r val
I have been searching for an online calculator that can give me accurate results, I recently found a web site that has a nice R value calculator; you can check it out at this address - http://www.reflective-foil-insulation.com/thermal_analysis.php?application=residential You can calculate all kinds of insulation products and applications, there is also lots of info about R value and U value.
R-value
Yes, materials with the same R-value have the same ability to resist heat flow. The R-value measures the material’s thermal resistance, so a higher R-value means better insulation.

The R value measures how well insulation materials resist heat flow. A higher R value indicates better insulation effectiveness, as it means the material can better prevent heat from escaping or entering a building.
The R-value of standard Batt insulation typically ranges from R-3.1 to R-3.7 per inch of thickness. However, the actual R-value can vary based on the specific materials and thickness of the insulation.
It is the measure of insulation against heat/cold afforded by varying thicknesses and composition of construction insulation materials. The higher the "R" Value the better the insulation characteristics.
The insulation value of stucco is relatively low compared to other building materials, typically ranging from R-0.2 to R-0.5 per inch of thickness.
The r-value of a sheet of newspaper is typically around 0.04 per inch thickness. This means that newspaper provides minimal insulation value compared to other building materials.
The "r-value" is a measure of the thermal resistance of a material. However, cloth itself does not have a standard r-value as it can vary greatly depending on the type of cloth, its thickness, and other factors. It is generally better to refer to specific types of insulation materials for standardized r-values.
The R-value of stucco typically ranges from 0.2 to 0.5 per inch of thickness. This is lower than most other insulation materials such as fiberglass or foam board, which have higher R-values ranging from 3.0 to 7.0 per inch. Therefore, stucco is not as effective as these materials in providing insulation against heat transfer.
The required R value for walls and roof insulation varies depending on your local building authority. The ideal R value will depend on the climate, altitude, latitude and exposure of your site and the form, amount of glazing,materials and use of the building.
