R arrowed labelling of data points on a plot
plot, r
Solution
You can use `arrows` function:
set.seed(1); ts.plot(x <-rnorm(10,0,1), ylim=c(-1.6,1.6)) # some random data
arrows(x0=1:length(x), y0=0, y1=x, code=2, col=2, length=.1) # adding arrows
text(x=1:10, y=x+.1, 0, labels=round(x,2), cex=0.65) # adding text
abline(h=0) # adding a horizontal line at y=0
Problem
I am looking to label data points with indices -- to identify the index number easily by visual examination. So for instance, ``` x<-ts.plot(rnorm(10,0,1)) # would like to visually identify the data point indices easily through arrow labelling ``` Of course, if there's a better way of achieving this, please suggest
