I wanted to add some text to a plot and got (R-1.6.0, Linux):

> text(x = c(1, 4), y = 5, labels = x)
Error in text.default(x = c(1766, 1895), y = 5, labels = x) :
        Object "x" not found

With the default value of 'labels':

> text(x = c(1, 2), y = 5, labels = seq(along = x))
Error in seq(along = x) : Object "x" not found

A scoping bug? :)

But

> text(x = c(1, 2), y = 5)

is OK. Doesn't give the labels I want, though. But why does it work, i.e.,
why is 'x' found in this case and not when I write out the default?
