It would work if you modified as follows:
plot(lm(Girth~Height))
Or alternatively,
fm1<-lm(Girth~Height);plot(fm1)

Yes, I am a newbie at R, but it is not the complex commands in R that
have me baffled, but simple data commands. For example, why does
something like:
> plot(Girth ~ Height)
*not* work after a command that allegedly loads the data:
> data(trees)
with the error message:
Error in eval(expr, envir, enclos) : Object "Girth" not found
but does work after the command:
> attach(trees)
?
