In an upcoming release of the rms package, all fit objects can be
printed using LaTeX if putting LaTeX code directly to the console
(this is optimized for Sweave). You will be able to say print(fit,
latex=TRUE).

Hello,
I am modeling some survival data wih cph (Design). I have modeled a
predictor
which showed non linear effect with restricted cubic splines. I
would like to
retrieve the se(coef) for other, linear, predictors.
The cph object has a "var". The vcov function is an extractor
function. You would probably be using something like:
diag(vcov(fit))^(1/2)
This is just to make nice
LateX tables automatically.
Are you sure Frank has not already programed that for you somewhere?
Perhaps latex.cph?
I have the coefficients with coef().
How do I do that?
Thanks,
David Biau.
