Using plot.zoo in the zoo package try this:

Lines <- "Bob.A         Bob.B            Tom.A        Tom.B

I'm fairly new to S-Plus and I need to get this done quickly. 
Suppose I

have the following fake data below:

 There are two companies, call them Bob and Tom. Each have two

 Sep            4          3              1        9

 Here is what I want to do: I want to make two different graphs, one

for

Bob and one for Tom. For each graph, plot both variables A and B. 
Connect the A values with a line, and connect the B values with a 
different type of line. So there should be two lines for each graph.
For the A line, at each time point, the letter A should be on the line.

And the same goes for the B line. Either R or S-Plus since they are

 I'm sure this is easy, but any help would be greatly appreciated.

 Thanks,

 Bill
