Rhelp is a plain text mailing list. It is not a project server. We don't 
exist to deliver code on command. We do exist to help with efforts at R 
coding. First you need to use an editor that does not create "smart 
quotes" by default. You should also start your code with library calls 
to load all necessary packages. I note this because GetBatchSymbols is 
not in package:quantmod. You should then show all the code from your 
efforts at investigation of objects' structure and properties and your 
efforts at plotting. Then describe what sort of problems you seem to be 
having in understanding the results and modifying them.
