[R] Identify command in R]

[David Kaplan]

Let me try to be more specific.

The x y coordinates are different because of NAs in the dataset.  In 
this analysis, a set of hat values (a measure of influence in 
regression) is given for each observation.  On the basis of the 
regression that was run to get these hat values, the sample size was 
1164 (one removed due to NA).  The length of the data set is 1165.  If I 
remove the NA from the data set, I can get identify to run.  What I 
would like to know is if there is a way to get identify to ignore the NAs?

 

Thanks in advance,
