To expand on Duncan's answer, you haven't replaced it. The following
should make that clear:
## starting in a fresh session

function (..., recursive = FALSE) .Primitive("c")

[1] "package:base"
> c <- 1
> find('c')
[1] ".GlobalEnv" "package:base"
> c
[1] 1
> rm(c)
> find('c')
[1] "package:base"
> c
function (..., recursive = FALSE) .Primitive("c")
The one provided by R, and the one you created, are not in the same
namespace.
To "recover" R's version, get rid of the one you created.Also, take a look
at the search() and conflicts() functions.
