I want to calculate the percentile of each CONC within ID=i and add as a
column "Percentile". I got some help from R-tutorial on percentile but I
am not able loop the function to calculate percentile/individual. So, I
want the calculation to include only the ID=1 DVs to calculate the
pecentile of conc=116. I truly appreciate your help.

new to R, analysis of latency data
...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
