[R] functions of functions

[Robin Hankin]

Hi

I have an application where my difficulty boils down to not
being able to define a function f() with the following properties:

f("sin",0:2,x)               #returns sin(x+0) + sin(x+1) + sin(x+2)
f(c("sin","cos"), 1:2,x)     #returns sin(x+1) + cos(x+2)
f(c("sin","cos","exp"),3,x)  #returns sin(x+3) + cos(x+3) + exp(x+3)

anyone?
