Dear Paul and Henrik,
I have a time series with some missing data points that i need smoothed
using Savitzky-Golay filter. Related question was asked  here
but no straight forward answer was posted. However, Henrik (cc'd here) did
ask related question on smoothing for reflectance here
which i have as well been unable to follow up. I will be glad if you could
assist me with some insights on the way forward or point to a relevant
source of help.

I have attached a simple test data plus the R code which only work with non
missing data. I will appreciate any possible assistance.
