mod <- lm(var1 ~ var2 + var3 + var4)
coef(summary(lm.D9))[, "Std. Error"]
if you prefer using column names.
coef() extracts the model coefficients from the lm object and the
additional content in a summary.lm object.
There are accessor functions for model objects and these are referenced
in "An Introduction to R" and in the See Also section of ?lm.
