Hello Bert,

Thank you for the reply and your clarifications. Yes, it might be helpful to 
look into R’s formal grammar to see how “function” parses input to delegate 
correct syntax. Is that accessible online?

Thank you,
Shelby

1. This is a plain text list; all html is stripped. So there is no red 
highlighting.

2. There is no "source code" for "function" -- it is a reserved keyword.
Or are you looking for R's formal grammar -- e.g. how it parses input to 
determine correct syntax?

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,
