I'm using R Version 2.6.1 under Windows XP.

The Problem: I'm using a function which is constructing a subset of a
dataframe. This dataframe is used in another function. The
structure is like this:
> inner = function (){
+ print('inner:')
+ print(s)
+ }
> outer = function(){
+ t = data.frame(list(X=1:10, Y=LETTERS[1:10]))
+ s = t[t[,'X'] < 5, ]
+ print('outer:')
+ print(t[, 'Y'])
+ inner()
+ }
> outer()
And the response in the R-Console is:
[1] "outer:"
[1] A B C D E F G H I J
Levels: A B C D E F G H I J
[1] "inner:"
Fehler in print(s) : objekt "s" nicht gefunden
(Error in print(s) : object "s" not found)
How can I make s reachable in inner?
Regards,
Matthias
