Dear all,
    I am searching the period of a time series usering R. 
    Is there some lag window functions  in R?
    Could you give me some books about spectral analysis usering R?
best wishes,

You might try being more specific. The easy, quick answer is "yes":

The original "book about R" , known in these parts as MASS, had quite
a bit.
