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.
