Here's something really strange.
********************************************************
R> x <- 1:5
R> x
[1] 1 2 3 4 5
R> test1
function (x)
{
structure(x, call = sys.call())
}
R> test1(x)
[1] 1 2 3 4 5
attr(,"call")
test1(x)
R> test2
function (x)
{
attr(x, "call") <- sys.call()
x
}
R> test2(x)
Error: stack overflow
********************************************************
Using the attr() form results in an endless loop ...
