Subject: dump() bug?
Is this a bug? Certainly it was not expected. dump() seems to prefer a
global definition over a local one. R 1.6.1 on Solaris 8 or NetBSD:
> ls()
character(0)
> dump("D", "D.q") # a global D() exists
> system("cat D.q")
"D" <-
function (expr, name)
.Internal(D(expr, name))
> D <- function(x) print(x) # now create a local one
> ls()
[1] "D"
> dump("D", "D.q")
> system("cat D.q") # here's the surprise
"D" <-
function (expr, name)
.Internal(D(expr, name))
>
The same thing happens with dump(list=ls(), "D.q").
