Counterpart for Matlab's 'feval'?
maybe you want something like this:
f <- function(x, FUN, ...){
FUN <- match.fun(FUN)
FUN(x, ...)
}
f(seq(-3, 3, 0.5), dnorm, sd = 1.1)
f(seq(-3, 3, 0.5), "pnorm", sd = 1.1)
but also take a look at ?optimize(), which will probably take you out
of the trouble of writing a new function yourself.
I hope it helps.
Best,
Dimitris

Subject: [R] Counterpart for Matlab's 'feval'?
Hi! I've just begun writing a program that searches for the minimum of a function with golden section search. In order to do this in a nice way I need a function that takes a function name and an argument and returns the function value for that argument, i .e just like Matlab's 'feval'. Is there any? Thanks before hand!
