See the definition of a bug in the FAQ.
> plot.default resets xaxp, and leaves xaxp reset when it exits:
xaxp is defined as
`xaxp' A vector of the form `c(x1, x2, n)' giving the coordinates
of the extreme tick marks and the number of intervals between
so it is redefined whenever axes are drawn. Many of the graphics par's are
reset when a plot is drawn. par("usr") is another one.
I don't see why you expected otherwise (and in particular why you expected
this to be documented under plot.default).
