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.
