[R] Identify command in R

[David Kaplan]

Hi all,

In using the identify command, I get the following message

 > plot(hatvalues(scireg3))
 > abline(h=.0154,lty=2) # plots a reference line at (k + 1)/n
 > identify(1:1165, hatvalues(scireg3),row.names(sciach))

Error in xy.coords(x, y) : 'x' and 'y' lengths differ
 

which doesn't allow me to see the observation number when I scroll over 
with the mouse.  What exactly is this problem and is there a way to 
override it?

Thanks in advance.
