get numbers contrary to complex number

[Daniel1_1]

Hello, i want to get a new idea from a key to get a complex number
For ex) there's numbers (1~10)
i want to get numbers except complex
so i wanna get numbers 4,6,8,9,10
i was trying to get

for(i in 1:10) {
+     check = 0
+         for(j in 1:i) {
+             if(i%%j==0) {
+     check = check + 1 }
+             if(check<2) {
+     break()
+     }
+     }
+             if(check>2) {
+     print(i)
+     }
+     }

But answer was 10. i don't know what happens... can you tell me the right solution?
Thank you

I think you are looking for composite numbers e.g.numbers that are not prime. I only need to change one thing in your code for it to work. Your code will always stop the loop because the check starts at 0 and might increment to 1 but will never get to 2 because you break the loop if check < 2 but it should be check > 2

# Your method with just some formatting changes
for (i in 1:10) {
  check = 0
  for (j in 1:i) {
    if (i %% j == 0) {
      check = check + 1
    }
    if (check < 2) {
      break()
    }
  }
  if (check > 2) {
    print(i)
  }
}


for (i in 1:10) {
  check = 0
  for (j in 1:i) {
    if (i %% j == 0) {
      check = check + 1
    }
    if (check > 2) { #changed this inequality sign direction
      break()
    }
  }
  if (check > 2) {
    print(i)
  }
}
#> [1] 4
#> [1] 6
#> [1] 8
#> [1] 9
#> [1] 10
