Hi Mayooran
It is better to keep your mails on rhelp. Others could answer too.

this will select **one** random number from indx so easier version is
start1 <- sample(indx,1))
> start2 <- sort(sample(start1+1,1))
> start3 <- sort(sample(start2+1,1))
these will select one random number from 1:start1 or 1:start2, again easier
version is
start2 <- sample(start1+1,1)

> grab.samp1 <- start1:(start1+n-1)
> grab.samp2 <- start2:(start2+n-1)
> grab.samp3 <- start3:(start3+n-1)
and this will just make vector of of 200 consecutive numbers. So
startn <- sample(indx,200)
gives you 200 random numbers from 1:N vector.
And this will give you list of m vectors with 200 consecutive numbers starting
randomly.
lll <- vector("list", m)
for (i in 1:m) {
lll[[i]] <- startn[i]:(startn[i]+n-1)
}
Is this what you wanted?
Cheers

Hello I am trying to generate samples from a bulk set of number for my research. So I need to get an output which contains various collection of samples, for example, sample1, sample2, sample3, Does anyone suggest any ideas?
