The readers cannot guess, what "binary representation of an rgb image i. e. 10001010" exactly is. Is this a logical vector, a decimal number or a character vector? Did you search in the forum for "lsb steganography" already? You will find a lot of corresponding threads.
I strongly recommend to remove the "ASAP" from the question. Pushing the readers is counterproductive, because it sounds impolite.

You can use bitset() and bitget() .
To extract the lsb you can use mod(YourImage,2) . To set new lsb you can do
YourImage - mod(YourImage,2) + NewLSBValue
