Thanks Arun.. I appreciate your time.. in making the generic script.
I believe that this is not a very trivial question..

Hi Jeff,
First of all I am not a good programmer in R.
I have a 2 line code in shell script using awk, head, tail and for loop
combination that accomplish this task.
So I thought of using R itself to do this task but I don't have any idea how
to do it in R.
Any way I will try to learn my own wh
s2<-fun2(dat1,dat2)
res2
# Unique StepNo Data1 Data2
#3 A 1 7 8
#8 B 1 4 5
ddply(res2,.(Unique,StepNo),numcolwise(mean))
A.K.

This is not a free do-my-work-for-me forum, this is a help-you-learn-R forum.
If you study the solution you have been given until you understand how it
works, and combine that with an understanding of indexing from the Introduction
to R document that comes with R, you should be able to complete
Hi Arun,
Thanks for your reply but your script is removing only one row( first row
and last row) for each Unique and StepNo combination and calculating mean
for the rest of rows.
For below data , your script removing the #'s rows perfectly.
But in reality I may need to ignore *say first 10 rows

Hello All,
I have a .csv file( contents shown) below, where I need to calculate
mean(for example) for only the rows highlighted in bold. (i.e. in this
example case I need to exclude the first row and last row(N=1) for each
"*StepNo*" column)
