Hi ,
I was trying to generate random data in R using the runif function. But
I am not sure how do I combine the x and y to get a 2d array/matrix in a
variable z.
As seen below I am getting the same numbers in x as 1 and in y as 2.1
respectively. I would like to get different & random numbers in x & y.
Please let me know.
x <- array(runif(N,1),dim=c(N,1))
> x
[,1]
[1,] 1
[2,] 1
[3,] 1
[4,] 1
[5,] 1
[6,] 1
[7,] 1
[8,] 1
[9,] 1
[10,] 1
> y <- array(2*x + runif(N,1)/10)
> y
[1] 2.1 2.1 2.1 2.1 2.1 2.1 2.1 2.1 2.1 2.1
Thanks & Regards,
Shweta.
