Hello:
How can I work around the conflict between the S3 and S4
illustrated in the example below? I'm developing a package that
requires a function in 'stats4', but when 'stats4' is attached, it
breaks my AIC function. I could give my AIC function another name so it
no longer uses the generic dispatch, but I wonder if there is another way.
Thanks,
Spencer Graves
