Yes, but you can still print(base::pi) and rm(pi) to get back to our flat
world, and you can't
assign("pi", 4, pos = "package:base")
Error in assign("pi", 4, pos = "package:base") :
cannot change value of locked binding for 'pi'
Just a feature of the search path. Morale: if you want base::pi, write
base::pi.
Try this:
old.pi<- pi
assignInNamespace("pi", 2.3, ns = "base")
pi
[1] 2.3
base::pi
[1] 2.3
Ah! assignInNamespace does an unlockBinding under the covers which
obviously is Evil(tm). The answer clearly is to do
assignInNamespace("unlockBinding", function (...) {warning("be safe");},
ns="base")
in your .Rprofile! Let's Keep R Safe, Folks!
