Not much

Error in plot(cf[, 1], type = "l", col = "black", xlab = "Time", ylab = "Correlation", :
object 'cf' not found
No object cf here.
It would be good if you make your code reproducible by putting a result of
dput(cf)
and make available other objects used for plotting. Or you can try to present some fake data illustrating your points.
