This is related to a problem that was fixed in 2015
https://github.com/wch/r-source/commit/38ea40dcd0353af16d35296ee621338c49ae48c9
The problem then was that auto-printing by typing an object to the console
would search for show() in the globalenv instead of in the methods
namespace.
The problem I would like to report is that it seems that when an S4 object
is printed with print(), a similar issue happens. I do realize that S4
objects should be printed with show() rather than print(), which would
solve the issue, but this still seems like a bug to me.
Example:
library(methods)
show <- function(...) message("hijacked!")
setClass("Test", representation(test = "character"))
test <- new("Test")
print(test)
# hijacked!
