I have a question for the group, perhaps someone can help me
figure this out. I've already looked in the help files and they were
no help to me.
I have a vector of values and I am plotting an ecdf graph.
1. How can i draw a continuous line through the ecdf points? (lines
and type for the plot with an ecdf object does not work)
2. Supposing I have this line drawn. I can add a vertical line of a
known x value which intersects the graph. How can I determine the
y value of the graph point that is intersected by the abline?
Any help would be appreciated.
Thanks in advance,
