What about:
set.seed(1001)
total <- 0
data <- vector("list", 30)
for(i in 1:30) {
data[[i]] <- runif(50)
}
set.seed(1001)
data[[23]] <- runif(50)

Subject: [R] set.seed and for loop
Dear All,
This is hard to describe so I made a simple example.
set.seed(1001)
total <- 0
data <- vector("list", 30)
for(i in 1:30) {
data[[i]] <- runif(50)
}
Let's call a data set runif(50).
While the for loop is running, 100 data sets are generated.
I want to restore 23th data set (the data set generated in 23th for
loop) without the loop.
I've tried set.seed(1023) runif(50)
but this is different data from the data set gotten from 23th for loop.
How can I get 23th data set without the loop?
Thank you,
Soyeon
