[R] Function objects as arguments of a function

[Tsumiyama Isao]

Hello, R users.

 In C (or C++) language, a function can be used as
an argument of another function as follows:

//  function used as an argument
void foo(int x)
{
    ...
}

// function using a function as an argument
void bar(void (*func)(int ), int arg1, int arg2)
{
    ....
}

//  The function 'bar' will be called as follows
int main()
{
    ....

    bar(foo, arg4foo, other_arg);

    ...
}

In R, can function objects be used as arguments of
a function? 

Thanks in advance from Japan
