For simplicity we'll assume my code looks as follows
plot(ecdf(1:1000))
which produces a diagonal line.
Ideally, I'd like to highlight or label in a different color certain X
values (say 50,55,60,65)
Is there a function which will allow me to do this?
Yes, ecdf() which returns a function
points(c(50,55,60,65), ecdf(1:1000)( c(50,55,60,65) ), col=c("red",
"green", "yellow", "blue") )
Draws colored points.
Could also use text() with same coordinates provided by a
"highlightvector" and ecdf(datavector)(highlightvector).
