[R] Identify command in R

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

Re: [R] Identify command in R]

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

Re: [R] Identify command in R]

Reading in between the lines a little, maybe you want lm(..., na.action = na.exclude) That should return missing values for the influence statistics when the predictor or responses is missing in the input. Hadley On Thu, Nov 20, 2008 at 4:19 PM, David Kaplan [EMAIL PROTECTED] wrote: Let me
