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.
