Hi Dennis,
 
Thanks so much, I will try change the code and see what happens. 
 
Many thanks,

Subject: Re: bestglm function and output in R

Hi: 

bestglmtest is your input data frame, is it not? From the names() line, 
you can see that it has no variable named BestModel that corresponds 
to a list containing a component named coefficients. 

Were you perhaps looking for 
output$BestModel$coefficients  ??
