[R] interpreting Weibull survival regression

[sms13+@pitt.edu]

Hi,
I was wondering if someone can help me 
interpret the results of running 
weibreg.

I run the following and get the 
following R output.
> weibreg(Surv(time, censor)~covar)
fit$fail =  0
Call:
weibreg(formula = Surv(time, 
censor)~covar)

Covariate           Mean       Coef 
Rel.Risk      L-R p   Wald p
covar     319.880    -0.002     0.998 
0.000

log(scale)          0.000     8.239 
3786.326               0.000
log(shape)          0.000     0.265 
1.304               0.000

Events                    172
Total time at risk        845891
Max. log. likelihood      -1609.4
LR test statistic         34.4
Degrees of freedom        3
Overall p-value           1.65026e-07


I would just like to find the estimated 
mean survival time as a function of the 
covariate in the model, but am not sure 
how to use this output to find that.
Any help would be greatly appreciated.

Thank you,
Steven
