I would like to be able to label each point in a scatter plot with
the numeric order of that point. for example, I create the following plot:
plot(e,n)
#
# now I go back and create my labels
#
for(i in 1:length(e)) { # lets say e <10
pc <- as.character(e_order[i]) # e_order has an
integer array 1,4,3,2... which is the order of e
points(e15[i], n15[i],pch=pc) # this will plot
0-9 as data labels
}
#
The above works for single characters. Now if the length of e[] is
greater than 9, the character string converted by as.character will
yield more than one digit. At this point, my labeling trick fails:-(
1) is there a way to create two character labels for a plot?
2) Or even better, is there a way to do what I am trying to
do. Label each point by its numeric order?
Thanks for your help.

I think you want to use text() x=1:15; y=16:30 plot(x,y) text(x,y, as.character(x), pos=4) ----- Original Message ----- From: "ableape" <renaldo at ableape.us> To: <r-help at stat.math.ethz.ch> Sent: Wednesday, October 18, 2006 4:59 PM Subject: [R] Labels for Points- 2 character labels?>I would like to be able to label each point in a scatter plot with > the numeric order of that point. for example, I create the following plot: > > plot(e,n) > # > # now I go back and create my labels > # > for(i in 1:length(e)) { # lets say e > <10 > pc <- as.character(e_order[i]) # e_order has an > integer array 1,4,3,2... which is the order of e > points(e15[i], n15[i],pch=pc) # this will plot > 0-9 as data labels > > } > # > The above works for single characters.
