where the first col is my variable x and the second is f(x). I've
obtained this from the result of a kernel density estimate so I
don't know the explict form of f(x) .
For some reason i want to integerate f(x) over a certain range using
integrate( ). So i want R to consider the above matrix as a function
where the first col is the argument x and the second is the
realization f(x).
I've tried as.function and vectorize but it didn't work out.
Could u help me do it?
Thanks
Maram
