We can only guess, because you did not supply the data. But I am quite sure, that the lines-data are outside the range set by plot, probable because it were "errors", i.e. differences to the original data. Try plot(testVar, col="red") lines(testError, col="black") or use xlim as parameter of plot Dieter ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
