Re: [R] Randomly split a sample in two equal subsamples

Thanks, but I just don't know how to translate that to a dataset with rows and columns. Initially, I was thinking about something like that: # Create some data: a <- c(10,20,15,43,76,41,25,46) b <- factor(c("m", "w", "m", "w", "m", "w", "m", "w")) c <- c(2,5,8,3,6,1,5,6) number <- c(1:8) myframe

Re: [R] Randomly split a sample in two equal subsamples

Hi Yoan, Please try ?sample. Suppose you have 1:n ids of total observations where n is even, you want to randomly split it into two subsamples, the following code should work. n <- 20 one.sample <- sort(sample(1:n, n/2)) another.sample <- (1:n)[-one.sample] Good luck. Wu - A R learner.

[R] Randomly split a sample in two equal subsamples

Dear all, I would like to randomly split a sample in two equally large subsamples. The sample data is stored as a matrix with each row representing an individual and each column representing some variable (e.g., name, age, sex, etc.); the first row contains the names of the variables; the first co
