I have created a data set that I can view but when attempting to use the function data() an error comes up as- Warning message:
In data(Brates) : data set ‘Brates’ not found
I'm not sure exactly what you are trying to accomplish. WDI() returns a data frame so the Brates object is already present in your environment and ready for use.
If you are trying to read in the objects from the .Rdata file you saved, you need to use load("Brates.Rdata").
