names() is a great function for finding out how to get info from
objects of unknown structure, so try:
names(out)

Hi there,

I am beginner in R and I have some basic question. Suppose I run a common procedure such as a t test or cox model like below:

out<-coxph( Surv(tstart,tstop, death1) ~ x1+x1:log(tstop+1) , test1,method=c("breslow"))

Which yields the following result:

Call:
coxph(formula = Surv(tstart, tstop, death1) ~ x1 + x1:log(tstop +
??? 1), data = test1, method = c("breslow"))

?????????????????? coef exp(coef) se(coef)???? z??? p
x1??????????????? -9.58? 6.89e-05???? 6.83 -1.40 0.16
x1:log(tstop + 1)? 6.90? 9.93e+02???? 5.63? 1.23 0.22
Likelihood ratio test=2.97? on 2 df, p=0.226? n= 120

Now I simply want to create an array (let "a") with the coefficients. I.e. I want

a<-c(-9.58, 6.90)

Generally how can take the elements I want from the output matrix above for further manipulation?

Thanks in advance for any answer!!

Now I simply want to create an array (let "a") with the coefficients. 
I.e. I want

Most probably coef will work here

If you had tried help.search
??"coefficients"
you would find several appropriate items.

Besides 

str(object) is also a good starting point for inspection of any object.
