Hi Henrique,
Thanks for the fast answer,
The only problem in your code, which I think I didn't mention in my message
is that I would like one different random sampling procedure for each 1 in
my vector
The way it was written, it samples only once and replace by every 1:
> x = as.matrix(c(1,1,1,1,1,1,1,1,1,1,1,1,1,1,1))
> replace(replace(x, x == 1, sample(0:1, 1)), x == 2, 1)
[,1]
[1,] 1
[2,] 1
[3,] 1
[4,] 1
[5,] 1
[6,] 1
[7,] 1
[8,] 1
[9,] 1
[10,] 1
[11,] 1
[12,] 1
[13,] 1
[14,] 1
[15,] 1
Thanks
