Hello,
The construct data.frame(cbind(...)) is not at all needed, the following
is much better.
dat1 <- data.frame(num, ave)
Also, I've modified the text() call a bit, in order to have R tell the
dat1$num corresponding to the (unique) max of ave, and with an extra
argument, pos. This would allow for placement of the label near the point.
p <- boxplot(dat1$ave, data= dat1, main= "Average Size", yaxt = "n")
text(1, , y = max(dat1$ave), label = dat1$num[which.max(dat1$ave)], cex
= .7, pos = 4)
Hope this helps,
Rui Barradas

but I don't understand
#I would like the labels that appear in the boxplot to be DATA$num values.
You want 26 values potted?

#Dear all,
#Could anyone help me with the following?
#DATA
num <- as.numeric(seq(100:125))
ave <- c(0.5, 1, 1.6, 2, 2, 2.3, 2.5, 2.4, 3, 3.2, 3.3, 4, 4.8, 3.5, 2.7,
3.1, 2.8, 3.5, 4.1, 2.0, 2.5, 2.1, 3.4, 2.5, 2.6, 7)
DATA <- data.frame(cbind(num, ave))
rm(num, ave)
#BOXPLOT
x11()
bp <- boxplot(DATA$ave, data= DATA, main= "Average Size")
identify(x= bp$group, y= bp$out, labels= DATA$num, cex = 0.7)
#I would like the labels that appear in the boxplot to be DATA$num
values.
#When I identify the outlier it appears a "1" when I would like to appear
a "26"
#Do you have any idea of how I could do that?
#Many thanks!
