Possible bug in termplot function (stats package) ?

I'd say that the burden of proof is really on your side, but how hard can it be:

x <- 1:10
y <- rnorm(10)
m <- lm(y~x)
m$call

lm(formula = y ~ x)

m$call$data

NULL

I see... indeed, thx for the answer and sorry for my stupidity. Should
have thought about that case. Still, I wonder why it is necessary to
go look for the data in a calling environment if it should be
contained in the model frame of the fitted object. Or am I again wrong
in assuming that's always the case?

Cheers
