Speaking of coxph... I noticed a silly inconsistency between summary.coxph and other modeling functions: > m <- summary( coxph( Surv(start, stop, event) ~ x, test2)) > coef(m) NULL > m$coef coef exp(coef) se(coef) z p x -0.02110521 0.979116 0.7951769 -0.02654153 0.98 > coef(summary(lm.D9)) Estimate Std. Error t value Pr(>|t|) (Intercept) 5.032 0.2202177 22.850117 9.547128e-15 groupTrt -0.371 0.3114349 -1.191260 2.490232e-01 > summary(lm.D9)$coef Estimate Std.

And while we're at it, if your "p" column was renamed "Pr(>|z|)" or so, then printCoefmat could have been used. Apart from significance stars (which you might well dislike), this also provides a nicer display of the p values themselves: > printCoefmat(summary(lm.D9)$coef) Estimate Std.
