Use

if input_bits(bit) == '0'

instead of

if bit == '0'

and similarly for the elseif statement.

bit is the index; input_bits(bit) is the character at that index from character vector input_bits.

It would have been better if you had posted your code as code (text) rather than a picture, then we could have modified it and run it to show how to fix it. I'm not going to type in your code, so I will just make a suggestion on how to fix it and let you modify your code to see if it works.

Change if bit == to if input_bits(bit) ==.
