Hi All,

I have a very simple question about a time series object: how to access
values for a particular year and quarter (say)?

Suppose, following

http://www.stat.pitt.edu/stoffer/tsa2/R_time_series_quick_fix.htm

I have read in data as a time series; here is how it looks.

*       Qtr1  Qtr2  Qtr3  Qtr4
  1960  0.71  0.63  0.85  0.44
  1961  0.61  0.69  0.92  0.55
    .     .     .     .     .
    .     .     .     .     .
  1979 14.04 12.96 14.85  9.99
  1980 16.20 14.67 16.02 11.61*

How do I access the value for 1961 quarter 3 (say)?
