Hello everyone,

I have these 2 vectors in a type="s" plot  ( reported below)
I would like to check the value of y at  z=seq(0,1440, by=60)

I think that I can do it  calculating a vector that report the position of
the value  of y < = z for which the difference to z is minimal.


But I also guess that there should be a built-in function like locator,
that provides, given same x  points, the y coordinates.

Does it  actually exist?

Thank you for your help

H.





x<-1:679
and y:
