Not much > plot(cf[,1],type="l",col="black", xlab="Time", ylab="Correlation", axes=F) 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. > > How should I erase this sencond line, it is suposed they have the same > data?
