Dear Professor, when I use the function of 'detrend' in 'dplR' package to detrend the trend of tree ring width I received an error that is "In (function (y, y.name = "", make.plot = TRUE, method = c("Spline", : Spline fit is not all positive". But when did the same process again this error did not occur and the chronology of the rwl file was without a negative value. I want to know whether the chronology is reliable. I also hope you can give me some suggestions to deal with the problem in a batch process. Thank you a lot in advance.
