Re: [R] calculating the mean of a random matrix (by row) and some general questions

Thanks for your advice! I found another method to solve my problem (on page 20 of the manual =) ). Here's my code # Set n and m to whatever you want n = 25 m = 10 # Build a random vector (here with exponential distribution) with lenght of n*m x = rexp(n*m,1) # Set up a factor in order to group
