Hi r-devel If you define a function named `show` or attach a package with an exported `show` function, then printing/vieweing S4 objects breaks. This is probably because the `print` function calls `show`, which is now masked.
Example: show <- function() {} > setClass("Person", slots = list(name = "character")) > tom <- new("Person", name = "Tom") > tom # error > methods::show(tom) # works The error was a surprise to me because I was under the assumption that `show` would be namespaced and therefore should not break. I'm wondering if this is intended behaviour, or if this is a problem. My intuition, and Hadley agreed on Twitter, is that defining a `show` method should not have such a grave effect on printing S4 objects.
