Re: FFTA encountered missing data a ...



Hi Ansley


One thing you could do, if there is just one missing timestep, is
to skip that first value by sending  variable[l=2:428]  to the function.

This work fine. But what would happen if the missing value is for example the 20th? or the range from 125 to 201?


Somebody on the list here might suggest the right way to deal
with missing time steps to get a good FFT analysis - a local
mean might be a better idea than the overall mean, as you'll
see from the example below.

When you say local mean are you talking about the individual Jan, Feb,... means? If so how do I can compute those means, and how do I can introduce their values within the corrected data frame.

Thanks in advance,

Antonio Rodríguez
