[R] Regression slope confidence interval

[Christian Hennig]

Hi list,

is there any direct way to obtain confidence intervals for the regression
slope from lm, predict.lm or the like?
(If not, is there any reason? This is also missing in some other statistics
softwares, and I thought this would be quite a standard application.)
I know that it's easy to implement but it's for
explanation to people who faint if they have to do their own
programming...

Christian
