Identify function does not work properly.
Esc button does not stop the process and R crashes. On qqplots graphic,
identify() does not find any points.

It is a serious problem, I can't identify points without crashing R now.




PS : Identify does not work on multiple graphics (par(mfrow=c(2,2))

Can you send a reproducible example of the crash (exactly the code +  
how are you running R) and the crash report, please? I'm not able to  
reproduce any crash.

As for terminating the identify, use <Ctrl>+<Click> (Mac equivalent of  
second mouse button). <Esc> doesn't do anything in a Quartz device in  
R 2.7.0. I'll update the documentation correspondingly, thanks for the  
hint.

            

      
      
      
    

        
Again - without an exact example it's impossible to tell whether it's  
a user error or something real.

Thanks,
Simon

            

      
      
      
    

        
How could it? That makes no sense (do you really know how what  
identify does? I'd suggest you read the help page.).

Ok, This simple example does not work :

x=rnorm(10)
plot(x)
identify(x)

Identify function find points when I clic on them, but I can't stop the
process. ESC key, or any other mousse button does not work. So I have to
close the quartz() window to stop the identify process and sometimes R
crashes.


The second problem is that the mousse does not focus on the window when I
call identify()

The third problem is in this example :

x=rnorm(10)
qqnorm(x)
identify(x)

Identify function does not find any points when I clic on them and there is
always a problem to stop the process...



Let's see another example :


x=rnorm(10)
par(mfrow=c(2,1))
plot(x)
qqnorm(x)
identify(x)

For this example, I don't know if I am right and I understand that identify
does not find points. Is this really a bug ?


I apologize for my english and I hope you understand me correctly.

Olivier.

Hi,
I did not see you wrote how to terminate identify.
<Ctrl>+<Click> works very well so there is no more problem of crash.


There is always the same problem with theses examples :

#1
x=rnorm(10)
qqnorm(x)
identify(x)

#2
x=rnorm(10)
par(mfrow=c(2,1))
plot(x)
qqnorm(x)
identify(x)

identify does not find any points.


Thank you for your help.
Olivier.

Correct, but it is user error.  From the help for identify:

      x,y: coordinates of points in a scatter plot.  Alternatively, any
           object which defines coordinates (a plotting structure, time
           series etc: see 'xy.coords') can be given as 'x', and 'y'
           left missing.

and qqnorm does not do a scatter plot of 'x'.  You need something like 
(look at qqnorm.default)

xx <- qnorm(ppoints(length(x)))[order(order(x))]
identify(xx, x)

(If there were missing values you would need to work harder.)

And please have the courtesy to use your real name and give a signature

Or just

xx <- qqnorm(x)
identify(xx)

at least for the default method.
