R help - Feb 2011 - Regarding Savitzky-Golay Smoothing Filter

Hi
When we use the sav_gol command in R , it shows an error which says: "
error in as.matrix". We've downloaded the necessary packages. Kindly
help us with this issue. If there is any other function to perform
Savitzky-Golay smoothing in R, please let me know.

With Regards
Reynolds

Would be okay to mention the package where your 'sav_gol' is located.
You could also provide your "session info" for others to see which
packages are loaded.

Guess you mean RTisean::sav_gol(). There is another implementation in
the 'signal' package. Personally I am still using a version you can
find by RSiteSearch'ing the mailing list 2002-2007.
