[R] RowSums Question

[cameron]

thanks Henrique

I have another question.

 Lets say i have a timeSeries table 
            A        B      C 
 1/1/90   NA      1       2 
 1/2/90   NA      1       1 
 1/3/90   NA      1      -1 
 1/4/90   NA     -1       1 
 1/5/90    1       1       1 
 1/6/90    1       51      1 

I want to count is.numeric.  since NA is not numeric 

            A       
 1/1/90   2      
 1/2/90   2
 1/3/90   2
 1/4/90   2
 1/5/90    3
 1/6/90    3


Thanks again :)
Cameron
