[R] R help?

[Greg Snow]

Use summary on the fitted lm object, i.e.:

> fit <- lm(y ~ x, data=mydata)
> summary(fit)

And the t-tests will be printed (along with a bunch of other stuff).
You can also save the results of summary if you want to use the t-values
and p-values for something else.

Hope this helps,
