Re: [R] missing values in autocorelation

[Joris Meys]

Could you specify the problem and give a minimal example that represents
your datastructure and reproduces the error? See also the posting guides :

[R] missing values in autocorelation

[nuncio m]

Hi all,
 I am trying to find the autocorrelation of some time series.  I
have say 100 files, some files have only missing values(-99.99, say). I dont
want to exclude these files as they represent some points in a grid.  But
when the acf command is issued i get an error.
Error in plot.window(...) : need finite 'ylim' values
In addition: Warning messages:
1: In min(x) : no non-missing arguments to min; returning Inf
2: In max(x) : no non-missing arguments to max; returning -Inf

Is this because of all the values in the time series is the same, if so How
can I specify a bad value when the acf command is issued.  Also is it
possible to return a flag(like, -999) of length the maximum lag for acf of
bad grid points so that I can keep the number of files same for input and
output

Thanks
nuncio
