Hi,
I have plotted a cdf using the ecdf function with plot().
Code would make this concrete.
I want to
highlight/identify points on the same plot. Also, because this is a
cdf I
am not sure of the y coords for the point, otherwise I thought of
using
highlight in the NCStats package.
The y coordinate is just ecdf(object)(x.value)
... since ecdf returns a function, you get to use it as a function.
Really
a beautiful tool. Thank you Martin Maechler.
Thanks
