Look at glm function.

glm(formula,family=binomial(link=probit))

Hope will help!

In the base package, look at the help for "glm" and for
"family".
The way R does this (which is, of course, the way S does it) is
somewhat unusual, although elegant once you get the idea, so it
might help to read the relevant chapter in (for example) Venables
and Ripley's book.
