Dear R users,

I have two time series


Calculate and plot cross correlation between two time series over nested time 
periods. Each point in either time series is for a week (not exactly a calendar 
week, but the first week in a calendar year always starts from Jan 1, and the 
other weeks in the same year follow that, and the last week of the year may 
contain more than 7 days but no more than 13 days).

The first time series A is stored in a compressed (.gz) text file, which looks 
like (each week and the corresponding time series value are separated by a 
comma in a line):
week,value
20060101-20060107,0
20060108-20060114,5
...
20061217-20061223,0
20061224-20061230,0
20070101-20070107,0
20070108-20070114,4
...
20150903-20150909,0
20150910-20150916,1

The second time series B is similarly stored in a compressed (.gz) text file, 
but over a subset of period of A, which looks like:
week,value
20130122-20130128,509
20130129-20130204,204
...
20131217-20131223,150
20131224-20131231,148.0
20140101-20140107,365.0
20140108-20140114,45.0
...
20150305-20150311,0
20150312-20150318,364

I wonder how to calculate the cross correlation between the two time series A 
and B (up to a specified maximum lag), and plot A and B in a single plot? 

Thanks and regards,
Tim
