[R] COnfidence intervals for estimates of linear model

[Daniel Brewer]

Hello,

I would like to calculate the 95% confidence intervals for the estimates
of a linear model and I just wanted to check that I am doing it correct.
 Is it just:

Estimate + 1.95996*Std.Error to Estimate - 1.95996*Std.Error

or is there another approach that doesn't assume a normal distrbution?

Thanks.  Apologies for my naiivity

Dan
