title: Why am I getting different answer for same algorithm on R studio desktop vs R studio cloud?
body: <p>I run this simple code from class on my R studio desktop(M1 pro MacBook Pro) and the answer is different to the answer I get on R studio cloud. On the MacBook, I get 239.3093 vs 237.7821 on cloud. Am I missing something?</p>
  <pre><code>A = matrix(NA,nrow = 50,ncol = 50)
  for (i in 1:50) {
    for (j in 1:50) {
      A[i,j] = sin(i) + cos(j)
    }
  }
  
  pivot.above = function(A, r, c) {
    A[r, ] = A[r, ]/A[r,c]
    for (i in (r-1):1) {
      A[i, ] = A[i, ]-A[i,c]*A[r, ]
    }
     A
  }
  
  for (i in 0:48) {
    j = 50-i
    A = pivot.above(A,j,j)
  }
  
  A[1, ] = A[1, ]/A[1,1]
  
  print(sum(A))
