Hi Rogerio: Thks a lot. It works. By the way, I have 2 related sides issues that need some help: (1) What I want to do is this - do modwt on original time series - do thresholding on wavelet coefficients - obtain the inversed smoothed and detailed components of the original time series using the thesholded coefficients. How can this be done ? mra accept the original time series as input. imodwt rountine will give me the inversed transformed in the form of original time series, instead of separating them into detailed and smoothed component. (2) Is there a way to make R giving me error messages in English instead of Chinese so that I can communicate with others easily Thks
rdporto1 <[EMAIL PROTECTED]> »¡¡G Airon, I don't think you have to find an English computer 'cause the following must work in your Chinese one :-) Let me explain. First of all, change your lines to xdata <- ckhdat$Adj..Close[1:1447] #names(ckhdwt.la8) <- c("w1", "w2", "w3", "w4", "w5","w6", "v6") note the # sign, i.e., DO NOT change the names before the function imodwt. This is because the function imodwt looks for the names created by the modwt function. If you need to change names, do it AFTER the reconstruction. I hope that it helps you.
