I couldn't quite understand exactly what graph you are looking for, so
I'd be unable to provide code. Couple of pointers, though.
- Put your data into a data frame and look at Rcmdr "Graphs" menu. It
can do many types of them, and it should give you enough examples to
get started with.
- Try plot(x, y) and see if it satisfies your needs
- Once you get working the command, try say playwith(plot(x, y))
- Quick-R  contains many good examples for beginners.
