[R] error using environment(f) <- NULL

[Carmen Meier]

Hi To all,
I found in the tread
http://finzi.psych.upenn.edu/R/Rhelp02a/archive/46740.html

the reply for

/> y <- 3 /
/> f <- function(x) y /
/> environment(f) <- NULL /
/> f(1)

/but this example (R 2.4.0) will cause an error:

The use of the NULL environment is not longer possible (translated)
The ?environment reports the NULL as possible.
is there any other way now ,to get the same result

Regards Carmen
