Prints coxreg objects

More "pretty-printing" than print.coxph, which is a fall-back for 'difficult' objects.

# S3 method for coxreg
print(x, digits = max(options()$digits - 4, 3), ...)

Arguments

x	A `coxreg` object, typically the result of running `coxreg`
digits	Output format.
...	Other arguments.

No value is returned.

Doesn't work with three-way and higher interactions, in which case print.coxph is used.
