I am not sure this is the right place to get help on this. The manual
was not actually part of R, I believe.
If you do not succeed in getting help here, you might try contacting

Hi Alnazar,
I looked at your question yesterday and was unable to find what a
"majority guessing" function is. I think it may be related to the
"Pandemonium" model of decision making, but that doesn't get me very
far. Could you give us a hint as to what this function is?

A combination of subsetting and ?substr should get you close to a solution.
If the middle sequence you referenced isn't always the same distance from
the first character, you may have to involve regular expressions to find
"the middle".

Your question is too vague. What do you know about R? What do you know about
KNN? What have you tried so far? You need to teach yourself enough about R to

How did you "check it out"? I still suspect a formatting issue.
Please use dput() to provide a bit of data from each, eg
dput(head(x1))
