R help - Jun 2005 - locator()

Dear Sebastian:

Here is a snippet of code that you may find interesting
for labeling points on the plane:

plane1 <- function(x,main1="") {
  plot(x,main=main1,ylab="  ")
  zz <- locator()
  text(zz$x,zz$y,
       labels=paste("(",round(zz$x,1),
         ",",round(zz$y,1),")",sep=""),
       pos=2,cex=.55)
    invisible()
}


Hope this helps!

Sincerely,
