Dear all! Please help me with a script or package to compute a Gaussian filter. I have a time series (like average mean temperature from 1901-2014) and I want to extract low, high and band pass frequencies using a Gaussian filter with 32 years window. Thank you very much! Best regards! Catalin [[alternative HTML version deleted]]

Hello Catalin, you could have a look on this link first for ideas in constructing your own script. http://stackoverflow.com/questions/7105962/how-do-i-run-a-high-pass-or-low-pass-filter-on-data-points-in-r Cheers!
