I have a set of data (in a matrix). I spliced a column out and parsed it as.ts (time series). I then plotted the time series but I found that it was very noisy. I wanted to smooth it out. However, I am having some problems smoothing and plotting the smoothed version.
> A <- as.ts(read.table(choose.files())) > x <- as.ts(A[,10]) > plot(x) > > plot(smooth(x)) plot(smooth(x)) looks exactly like plot(x). Also, > StructTS(x) Error in optim(init[mask], getLike, method = "L-BFGS-B", lower = rep(0, : L-BFGS-B needs finite values of 'fn' The HoltWinters smoothing or the Kalman smoothing don't work either for various errors... I'm not quite sure what's wrong.
