Hello, I wonder if someone could help me with the following: I have generated 10 000 values from rnorm and now I want to randomly replace 500 of those with NA. The problem is that values indexed between 6-10,16-20,26-30.... only should be considered for replacement. Any suggestions?

Hello Eik: Thanks. I do not need to sample. Essentially, I have a do loop which produces 24 vectors of length of some length (say k=300) and 24 matrices of 300x300. Then, I simply need to? take the averages of these 24 vectors and matrices: x=(x1+x2+...+x24)/k y=(y1+y2+...+y24)/k I am just looking for ways to do this in a do loop, which requires initialization (to 0's) of x and y. My

Is there as way to initialize a vector (matrix) with an unknown length (dimension)? NULL does not seem to work. The lines below work with a vector of length 4 and a matrix of 4 x 4. What if I do not know initially the length/dimension of the vector/matrix? All I want is to add up (accumulate)? the vector and matrix as I go through the loop. Or, are there other ways to accumulate such vectors
