Error unexpected symbol how can I fix this ?

It is very difficult to work from an image. Please include a Reproducible Example in future questions.

In the image, the line that starts with

regModel <- glm(num ~ age

ends with

) summary(regModel

You cannot include the summary function on the same line as the call to glm()

The second line of code sets the family argument of glm to name of a distribution, which is not a valid value. The value binomial() that was used previously is valid. Also, you cannot set na.action to an action. I would leave out that argument unless you know you need it.

The third line of code begins with =, which is not allowed.
