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 column contains the individual number (1:n, for n

individuals); the number of individuals is even (so, the overall

number of rows is odd).

I found similar threads (like "random subset"), but I don't know how

to apply the information from them in my case. Could somebody help me

a little bit? Thanks in advance!

Yoan
