R help - Mar 2009 - programing for partial maximum likelihood for cox models with two covariate

dears,
I like two write a program with R to estimate  the coefficients of covariate,I
like two know the original program for this programing for partial maximum
likelihood for cox models with two co variate.

I did it with coxph command,

thanks

Loading required package: splines

function (formula = formula(data), data = parent.frame(), weights,
     subset, na.action, init, control, method = c("efron",
"breslow",
         "exact"), singular.ok = TRUE, robust = FALSE, model = FALSE,
     x = FALSE, y = TRUE, ...)
{
     method <- match.arg(method)
     call <- match.call()
     m <- match.call(expand.dots = FALSE)
     temp <- c("", "formula", "data",
"weights", "subset", "na.action")
     m <- m[match(temp, names(m), nomatch = 0)]
     special <- c("strata", "cluster")
     Terms <- if (missing(data))
