Hi,

  I'd like to move from excel to R because our dataset are so large. Here's
what my data looks like:

Transaction Rate   Run#       Transaction Type        Location    Latency in
Seconds
                   10        1                       Order                 
A                            0
                   10        1                       Order                 
B                            3
                   10        1                       Order                 
C                            1
                   10        1                       Order                 
D                            2
                   10        1                       ACK                   
A                            0
                   10        1                       ACK                   
B                            5
                   10        1                       ACK                   
C                            2
                   10        1                       ACK                   
D                            2
                   10        1                       FILL                   
A                            0
                   10        1                       FILL                   
B                            2
                   10        1                       FILL                   
C                            3
                   10        1                       FILL                   
D                            2

- we have about 1000 runs per transaction rate (run# 1..1000)
- we have 50 transaction rates (transaction rate 10..500 incrementing by 10)

We'd like to be able to create a graph where:
- Y axis = 95 pecentile latency of transaction type data (order, ack, fill)
- X axis = transaction rate

I've read the basic doc, created some simple plots, could someone get me
going in the right direction?

tia,
jd
