Hello Jiefei,

Missed this in the subsequent emails. That is a very intriguing article, but I do not believe that it quite answers my question. Regardless, I will review it, so thank you for sending it my way!

Respectfully,
Shelby

Hi Shelby,

Not quite sure what you are trying to do. Mine might be off-topic but have you seen this document?

http://adv-r.had.co.nz/Functions.html#function-components<http://mx1.njhealth.org:32224/?dmVyPTEuMDAxJiYzZDQ2Y2Y3YzhmYmIwZmMzMz01RDcyOTJGNl81MzQ2N180NjY0XzEmJjBjMTRiYjE5NTI5MjI2MD0xMjMzJiZ1cmw9aHR0cCUzQSUyRiUyRmFkdi1yJTJFaGFkJTJFY28lMkVueiUyRkZ1bmN0aW9ucyUyRWh0bWwlMjNmdW5jdGlvbi1jb21wb25lbnRz>

It illustrates the components of a function.

Best,
Jiefei

Hi all,

I have been attempting to access the source code for the keyword “function” to better understand how it assigns and stores logical inputs, like in the subset() [base] function. Does anyone know how I can access the source code for this?

For example, if I have
norm <- function(x){
      sqrt(x%*%x))
}
I am looking for the source code for the “function” portion, highlighted in red.

Thank you for your time and assistance,
