[R] get: problem with environments

[Martin Ivanov]

 Thank You very much for Your replies.
Dear Michael,

"Does this persist after a new session (perhaps running as R --vanilla) and/or reinstall?"
Yes, it does. After running R --vanilla, still there are 4 contexts more on the call stack.
 
"You didn't show us how you tried to use parent.frame()"
I did it like this:
testfun1 <- function (x1) {
 a1 <- 1;
 sapply(X="a1", FUN=get, envir=parent.frame(x1));
}

testfun1(x1=1);

The above code never succeeds no matter what a number I give to x1.

" 3. Why does the number of contexts in the call stack differ in R and in rkward?
 It shouldn't. This is an issue that needs further sorting out."

Here is some more info on my setup:
