How to do it...

Perform the following steps to fit a generalized linear regression model with the Binomial model:

  1. First, we examine the first six elements of vs within mtcars:
        > head(mtcars$vs)
        Output:
    
         [1] 0 0 1 1 0 1  
  1. We apply the glm function with binomial as the family object:
        > lm1 = glm(vs ~ hp+mpg+gear,data=mtcars, family=binomial)
> summary(lm1)
Output:
Call:
glm(formula = vs ~ hp + mpg + gear, family = binomial, data =
mtcars)
