application of ridge to all predictors

[carol white <wht_crl@yahoo.com>]

Hi,
It might be a primitive question but how do you specify all predictors in ridge function?
suppose that I have 100 predictors and I want to apply ridge to all 100 variables. instead of putting the name of all variables separated by "," (see 2nd code line below),  which notation should I use so that ridge would be applied to all variables?

usage of ridge function
ridge(..., theta, df=nvar/2, eps=0.1, scale=TRUE)
fit1 <- coxph(Surv(futime, fustat) ~ rx + ridge(age, ecog.ps, theta=1),

              ovarian)
