Dear R-helpers,
I try to use nested R-functions as follows:
help1 = function(){
x = 1
help2()
}
with
help2 = function(){
if (x == 1)
cat("Hello world x = 1")
}
If I compile these functions and run help1()
an error message occurs
Fehler in help2() : objekt "x" nicht gefunden
in english "error in help2(): object "x" not found"
If I change help1 to
help1 = function(){
x <<- 1
help2()
}
so that "x" is now defined at the global environment it works fine.
But the problem is, now "x" is defined also outside of help1 and this is
not desired !
Is there any usable solution for this problem?
But, the original problem is to assign new values for "x" in help1 inside
help2 !
Thanks in advance
Jörg Betzin
