Rather than asking for a tutorial on data management, you should:
a) read some introductory texts (look for "contributed" at the main r- 
project site)
b) read the Posting Guide  [ ... or reverse a) and b)  ]
c) construct a prototypical data object in R and using the skills  
exemplified in hte Posting Guide post a minimal example of what you  
are starting with and what you expect.
