Dear All,
I have a matrix m of the form
m
[,1] [,2]
[1,] 9072.302 0.00000004462366
[2,] 9086.811 0.00000005628169
[3,] 9101.320 0.00000007126347
[4,] 9115.830 0.00000008986976
[5,] 9130.339 0.00000011260000
[6,] 9144.848 0.00000014018405
[7,] 9159.357 0.00000017344229
[8,] 9173.866 0.00000021363563
[9,] 9188.375 0.00000026389996
[10,] 9202.884 0.00000032406678
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
