R help - Feb 2002 - identify with boxplot

Hello,

In a toy example below, there are some outliers which I would like to
mark with their rownames. However, it seems that identify(...) does
not work together with boxplot?

set.seed(1)
x<-data.frame(rcauchy(20))
rownames(x)<-letters[1:20]
boxplot(x)
identify(x,labels=rownames(x))



Thanks for any suggestions,

Remigijus                          mailto:remigijus.lapinskas at maf.vu.lt

You need to supply horizontal coordinates to identify -- e.g.,

 > set.seed(1)
 > x<-rcauchy(20)
 > names(x)<-letters[1:20]
 > boxplot(x)
 > identify(rep(1,20), x, labels=names(x))

(If you want to get row names from a data frame, that would work too.)
