How to incorporate interaction terms in the formula

[mudappathir]

Hi,
How do I incorporate multiple variables and their interaction terms in the coxph formula? Instead of mentioning [*] can I provide variables programmatically?

I designed the package to accept every possible formula type, including interactions. Can you show what you have tried, perhaps?
