Allow Creation of multiple data frames in R

Need ability to create multiple data frames to be used within the Query Editor or within the R Visual.

For example you have one data frame that contains data for each county within the united states. Then you need a second data frame that has store locations, Points(lat, long)... Thus, the mapping visual needs one data frame for geographical data and a second one that needs to have lat long for store location (points). Thus, there would be two data frames supplying the information.
