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
> myfun()
[1] 33 63 93 123 153 183 213 243 273 303 333 363 393 423 453 483

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.
