basehaz() in package 'Survival' and warnings() with coxph

I have a couple of questions with regards to fitting a coxph model to a data
set in R:
I have a very large dataset and wanted to get the baseline hazard using the
basehaz() function in the package : 'survival'.
If I use all the covariates then the output from basehaz(fit), where fit is
a model fit using coxph(), gives 507 unique values for the time and the
corresponding cumulative

basehaz() in package survival and warnings with coxph

For resloution you are going to have to give me a working example of the

Also, per the posting guide, what is your sessionInfo()?
