[R] [bug] spdep package?

[Henrik Bengtsson]

It turns out that that 'x' comes from the spData package and lives
inside that package (part of its namespace).

> spData::x
 [1]   0  30  60  90 120 150 180 210 240 270 300 330 360 390 420 450

This is conceptually no different from other objects in package
namespace, although we are more used to seeing functions and not data
object.  Another well-known example of this is:

> base::pi
[1] 3.141593

So, this 'x' is *not* in your global workspace and you cannot remove
it without unloading the package.
