R: Bell Coefficients Calculation
Bell Coefficients Calculation
Description
This function calculates Bell coefficients as described
on p.134–139 of Comtet (1974) for calculating high order
derivative of composite function f(g(x)) wrt x , say.
Usage
Bell(n)
Arguments
n
Derivative order n > 1
.
Details
Bell
calls the functions in package partititions ,
see http://cran.r-project.org/web/packages/partitions/partitions.pdf .
Note
Combinatorial computation intensifies as n
increases.
