R programe give me an error:

As Uwe said, this seems very unlikely. If you can show us
a clean, reproducible example we may be able to help. There's
no obvious reason why the variable n should have existed at the
time of your first run (radon.bugs.1) and then disappeared in
the process of running plot(radon.bugs.1); print(radon.bugs.1).
I suspect you are working through material from Andrew Gelman's
book (since he has some radon examples)?
[Uwe: one reason to chop out previous code/data is that if
one posts via gmane, it complains if you don't have enough 'new
stuff'. Sigh.]
Well, then the answer seems to be "don't use gmane" if it does restrict
its users in such a way. Looks like I am too old fashioned ....
Best,
Uwe
