Well, I don't know what is in stop.txt, but I will assume it is a
string of numbers or strings separated by the end of line character and
then a terminating EOL. Read it in as you have it and then:
b <- b[-21]
If you are reading in a dataframe, simply use what you have and then do:
b <- b[-21, ]
and you should have what you want, or perhaps you want
b[21, ] <- NA # indicate row 21 as a missing value
