[R] S4 Question; show generic method

[stephen sefick]

Hello,

I changed the name of a function, and updated my R packages with
update.packages(ask=FALSE), and I have had a curious (to me) change in show
method. I am developing a package, and a generic show method I defined for
my S4 class is not autocalled when I type the object name - object_name;
however, the show(object_name) works as expected. I have included the
output from sessionInfo():

R version 3.3.2 (2016-10-31)
Platform: x86_64-redhat-linux-gnu (64-bit)

other attached packages:

I appreciate any help with this problem.
kindest regards,

Stephen
