lm function

Hi, How can I extract the standard deviation of the coefficients when
using the lm function.  I know ____$coefficient gives me the individual
betas.  thank you

$coefficient is not the recommended way to get the coefficients.

use coef(your.model) for the coefficients and vcov(your.model) for their
variance matrix, so that sqrt(diag(vcov(your.model))) are the standard
errors.
