[R] how to show a plot without overlaying the text on top of the another text?

[Jim Lemon]

Hi Marna,
Your request made me think that a simple manual label placing function
might be useful to some people.

placeLabels<-function(pointer=TRUE,cex=1,labelcol=par("fg"),
 bg="white",border=par("fg"),pointercol=par("fg")) {

 cat("Enter a blank label to finish\n")
 nextlabel<-"XXX"
 while(nchar(nextlabel)) {
  cat("Click on a data point\n")
  datumxy<-locator(1)
  cat("Click on the label position\n")
  labelxy<-locator(1)
  nextlabel<-readline("Enter the label - ")
  if(nchar(nextlabel)) {
   if(pointer) segments(datumxy$x,datumxy$y,labelxy$x,labelxy$y,
    col=pointercol)
   boxed.labels(labelxy$x,labelxy$y,nextlabel,col=labelcol,
    bg=bg,border=border)
  }
 }
}

All I have to do is work out how to get it to automatically switch
back to the console window for the label entry.

Jim
