Question with R - Bioinformatics, Applied Statistics

Hi There,

I have a question regarding R, and I am wondering if anyone can help me.

Here is a code that I would like to understand:

squareFunc <- function(f) {
g <- function(x) {
f(x)^2
}

return(g)
}

sin.2 <- squareFunc(sin)

sin.2(1)


In the above code, function sin is nested in suquareFunc, which also has a function g inside.

I am having hard time understanding this code.

For example, if I was asked to write this code, mine would look like:

squareFunc <- function(f) {
g <- f^2
return(g)
}

sin.2 <- squareFunc(sin)

sin.2(1)

and this does not work.


I feel that argument ''f'' in in squareFunc(f) should be passed on to the function ''g'', but what g has is (x).

Obviously the first code works if I type it in R, but I would like to understand how it works.

I may not be asking the right question, but if you can see where I am confused at and can help me to understand it, that would be great.

Thank you very much in advance.

Mayumi
