Hello,


I found a dangerous issue in the library spdep. I get variables x and y
that cannot be removed by rm() and I don't don't how they show up. Can
anyone reproduce this?

I cannot.

This is *very* unlikely to be a bug. People should always exercise a great deal of caution about conjecturing bugs when they encounter a
phenomenon that they don't understand.

What do you see if you simply do "ls()"?  (After loading spdep.)
I.e. do you see an "x" listed as an object in your workspace/global environment?

What does find("x") return?

It puzzles me that your sessionInfo() doesn't show something like:

other attached packages:
[1] spdep_0.6-13  Matrix_1.2-10 sp_1.2-5

There are probably other issues that you have not told us about.

cheers,

Rolf Turner
