[R] exclude

[Val]

Thank you Bert and Jim,
Jim, FYI , I have an error message generated as

Error in allstates : object 'allstates' not found

Bert, it is working. However, If I want to chose to include only mos years
example, 2003,2004,2007 and continue the analysis as before.  Where should
I define the years   to get as follow.
      2003 2004  2007
  AL    2    1       1
  NY    1    1      2

Thank you again.
