Subject: [Rd] identify(...plot=F) (PR#1157)
Message-ID: <200111020144.CAA04490@pubhealth.ku.dk>


If I execute, e.g.

> x <- round(runif(20,0,1),2)
> y <- round(runif(20,0,1),2)
> plot(x,y,xlim=c(0,1),ylim=c(0,1))
> identify(x,y,n=1,plot=F)

then I get the index of the identified point printed in the command
window, and ***initially*** the index is NOT displayed in the
graphics window (which is the behaviour I had hoped and expected
to obtain by setting ``plot=F'').

BUT THEN if I lower and then raise the graphics window, poof!!!
the index appears, unwanted, in the plot.

I think a workaround is to issue the identify command as

> identify(x,y,n=1,col=0)

but still, shouldn't the function work as advertized?
