[R] Randomly split a sample in two equal subsamples

[Wu Gong]

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
