incidence rates and rate ratios in S-Plus

[Pedram Sendi <psendi@swissonline.ch>]

Dear All,

Say I have a dataset with 100 cases and for each case I have the
information whether a disease has occurred (dis = 1 or 0), and
information about age, sex, and follow-up time (fu). I would like to
estimate the incidence rate and incidence rate ratio (male versus
female), adjusted for age. Any help re how to do that in S-Plus will be
greatly appreciated. Would a Poisson regression model be appropriate?

Many TIA,
Pedram
