Good day everyone! I would appreciate if anyone can help me regarding the following: I would like to implement the Whittaker-Henderson smoothing to the raw data on the attached .txt file, based on the description on this link:
https://artax.karlin.mff.cuni.cz/r-help/library/pracma/html/whittaker.html On the attached .txt file, The x's are the independent variables and the y's are the dependent variables. The signal to be smoothed is y, lambda = 1600 and d = 2. Can anyone please send me a sample R script, or a link to an R script which I can adapt, where I can get both the (1) smoothed graph and the (2) smoothed values of y for each x given, and then import both the smoothed graph and the smoothed values of y to Microsoft Excel? Thank you very much. Regards, Percy
x y 0 6.35 1 2.99 2 1.97 3 1.94 4 0.90 5 0.88 6 0.65 7 0.84 8 0.77 9 0.67 10 0.82 11 0.80 12 0.75 13 0.82 14 0.74 15 0.43 16 0.88 17 0.74 18 0.72 19 0.55 20 0.60
