Error in if statement in r

This might be a silly question, but since I could not find the way to search it, I wanted to ask. I have the code below:

(m is a numeric value defined earlier)

if (0 < m <= 1.00){  
    print("a") 
  } else if (1.00 < m <= 2.00){  
      print("likely benign")
  } else if (2.00 < m <= 3.00){  
      print("b") 
  }   else if (3.00 < m <= 4.00){  
      print("c") 
  }   else if (4.00 < m <= 5.00){  
      print("d") 
  }   else if (5.00 < m <= 6.00){ 
      print("e")
  }   else{  
      print("f") 
  }

It gives the error: Error: unexpected '}' in " }"

but I used if in exactly the same way on the upper part of the code and there is no error from that part. How can I fix this? Thanks in advance.
