Hi, Not exactly sure what you mean, but if you want to run a poisson regression and then look at the coefficients, then this is what you need:
poisson.model <- glm(response ~ predictor, family = "poisson") summary(poisson.model) Will give you the intercept and slope. Since poisson regression uses a log link to model data linearly, the coefficients are in the log scale.
