If object is user defined is:

 

object$df.residual

 

the same thing as

 

df.residual(object)

 

This is my first time to encounter the $ sign in R, I'm new.  I'm
reviewing "summary.glm" and in most cases it looks as though the $ is
used to extract some characteristic/property of the object, but I'm not
positive.

 

Thanks
