[Rd] What functions are called internally in R to resolve what variable is referred?

[thmsfuller066 at gmail.com]

Hello All,

If I refer to a variable 'x', 'x' will be searched in the current
frame or the parent frame, or the parent of the parent frame, etc.,
until it is found (or not found at all)? Could you please show me what
code in R source that handles this? Is it in the C code or the R code?

Thanks,
Tom
