.Internal functions such as rnorm cannot be retrieved in this way as
far as I know. You may have to download the source and find it
direclty.
In this particular case you can find the implementation of rnorm with
grep -rn --include=*.c '"rnorm"' .
# ./src/main/names.c:449:{"rnorm", do_random2, ...
grep -rn --include=*.c 'do_random2(' .
# ./src/main/random.c:131:SEXP attribute_hidden do_random2(SEXP
call, SEXP op, SEXP args, SEXP rho)
Starting with line 131 in src/main/random.c you can follow the chain of
macro executions and calls to see how rnorm is actually implemented.
