[R] Error in family$linkfun(mustart) : Value 1.125 out of range (0, 1)

[Dinuk Jayasuriya]

John/Michael, thanks for your comments.

I get the following error when I run my code (the code is attached as is a section of the data set):
Error in family$linkfun(mustart) : Value 1.125 out of range (0, 1)

If anyone can please provide assistance that would be much appreciated - I'm not sure if it's something wrong with my dataset or a bug in the program "list" 

Many thanks,
Dinuk
