Ok,  I over reacted and I should let the package maintainers
qualify what is a bug or not. My point is that it is surprising to have
access these variables in the global environment when loading the spdep
library.

I normally I would expect the following

 rm(list=ls())
 myfun <- function(x){
        y+ 33}
        
> myfun(x)
> Error in myfun(4) : object 'y' not found

But this is not cool

You are right. My apologies. I confused sessions when I pasted the
sessionInfo.  Allow me to correct.

I think Henrik Bengtsson has identified the issue see the next thread.
